Machinery Breakdown & MLOP Insurance Malaysia

Your fire insurance and IAR policy cover a lot. But neither covers your CNC machine burning out its motor, your compressor seizing from bearing failure, or your generator short-circuiting during a power surge. Those are internal machinery faults, and they're explicitly excluded from every fire and property policy in the Malaysian market.

Kevin Hoong, ACII, Managing Director, Foundation. Reviewed 8 September 2026.

Machinery breakdown (MB) insurance fills that gap. It covers internal mechanical and electrical faults that destroy or damage your equipment. MLOP (Machinery Loss of Profits) covers the revenue you lose while that equipment is being repaired or replaced.

This guide covers:

• What MB insurance covers (and what it doesn't)
• How MLOP works as the "business interruption" for machinery claims
• MB vs Fire vs IAR vs EEI comparison
• Premium factors and indicative rate ranges
• Standard exclusions and optional extensions
• How MB/MLOP fits your factory's P&E programme
• Claims process and intermediary submission requirements

Why Machinery Breakdown Insurance Exists

Fire insurance covers named perils: fire, lightning, explosion. IAR extends that to accidental damage, theft, water damage, and impact. But both policies contain a standard exclusion for mechanical and electrical breakdown. This means internal faults originating within the machine itself are not covered under any property policy.

MB insurance is an engineering class policy, not a property class policy. It was designed specifically to cover the perils that property policies exclude. The coverage trigger is an internal fault, not an external event. If a bearing seizes because of metal fatigue, that's MB. If the same machine is damaged by a forklift crashing into it, that's IAR.

For any factory running production machinery, MB and IAR work together. IAR covers external damage. MB covers internal failure. Without both, you have a gap in your equipment protection.

MB vs Fire vs IAR vs EEI: What Covers What

This is the single most important table for factory owners to understand. Each policy class covers different cause-of-loss categories. Overlap is minimal.

Machinery Breakdown and MLOP are individually underwritten. The single biggest lever you control is the quality of your maintenance and inspection records, because that is the evidence an underwriter actually prices against.

GP = Gross Profit. MLOP sum insured is calculated based on the annual gross profit of the business or production line.

Standard MB Exclusions

Understanding what MB does NOT cover is just as important as knowing what it covers. Most exclusions exist because another policy class handles that peril.

The key takeaway: MB handles internal faults. Everything external (fire, flood, theft, impact) belongs to your property policy. And specialist equipment (boilers, pressure vessels, electronic equipment) has dedicated engineering policies. A complete factory programme needs all of them working together.

Machinery Breakdown Claim Scenarios

These scenarios illustrate how MB and MLOP claims work in practice for Malaysian industrial operations.

Scenario 1: Injection Moulder Motor Burnout

A plastics factory in Shah Alam runs 12 injection moulding machines on a 24/7 schedule. One machine's main drive motor suffers insulation breakdown during a shift change. The motor seizes, damaging the gearbox and cracking the barrel.

Without MB: the factory absorbs RM237,000 in repair costs. Without MLOP: they also absorb RM300,000 in lost revenue. Total uninsured loss: RM537,000.

Scenario 2: Cold Room Compressor Seizure

A frozen food distributor in Johor operates three large ammonia compressors. One compressor's main bearing seizes due to metal fatigue, destroying the crankshaft and connecting rods. The remaining two compressors can't maintain temperature across the entire facility.

The rental compressor expense shows why MLOP's "increased cost of working" provision matters. Without it, the distributor would have to choose between renting emergency equipment out of pocket or losing RM2M+ in frozen stock.

Scenario 3: Power Transformer Failure

A manufacturing facility in Penang's Bayan Lepas Free Trade Zone loses its 11kV/415V power transformer to an internal winding fault. The transformer serves the entire production floor. Lead time for a replacement transformer from the OEM: 16 weeks.

This is the type of scenario where the MLOP claim dwarfs the MB claim. The physical damage is RM770,000. The lost revenue is RM2,000,000. Factories that skip MLOP to save on premium are betting that their most critical equipment won't fail.

Scenario 4: CNC Machine Bearing Failure

A precision parts manufacturer in Rawang operates a fleet of 5-axis CNC machining centres. One machine's spindle bearing fails during high-speed cutting, destroying the spindle assembly. The spindle is a proprietary component from the German OEM.

MB/MLOP in Your Factory's P&E Programme

MB and MLOP don't work in isolation. They're part of a layered engineering insurance programme that covers different aspects of your physical risk. Here's how the pieces fit together for a typical Malaysian factory.

A factory with IAR but no MB has a coverage gap for the most common equipment failure mode: internal breakdown. A factory with MB but no MLOP has the machine repaired but absorbs the revenue loss during downtime. The complete programme covers both.

The Claims Process for MB/MLOP

Immediate Steps After Machinery Failure

Critical point: Do not dismantle the machine before the loss adjuster inspects it, unless safety requires immediate action. Dismantling destroys evidence of the cause of failure, which can jeopardise your claim. If emergency repair is needed, photograph everything before starting work.

Documentation Required

MB claims are technical. The insurer will appoint an engineering loss adjuster (not a general adjuster) who understands machinery. Having these documents ready speeds up the process significantly.

• Machine purchase invoice (original cost, date, supplier)
• Maintenance records for the failed equipment (last 12-24 months)
• OEM service reports and inspection records
• Photographs and video of the damage before dismantling
• Root cause analysis or preliminary diagnosis from your maintenance team
• Repair quotations (minimum 2, preferably including OEM)
• For MLOP: production records, revenue data, and evidence of lost orders/contracts

FAQ

Does my fire insurance or IAR cover machinery breakdown?

No. Both fire and IAR policies explicitly exclude internal mechanical and electrical breakdown. Fire covers external fire damage to your machine. IAR covers accidental external damage (impact, water, theft). Neither covers a motor burning out, a bearing seizing, or a shaft breaking from metal fatigue. That's what MB insurance is for.

Is machinery breakdown insurance mandatory in Malaysia?

MB insurance is not legally mandatory. But many bank financing agreements require it when machinery is financed or leased. Some multinational companies also require MB coverage as a condition of supply chain qualification. For factories where equipment is the primary revenue-generating asset, it's a financial necessity even without a mandate.

What's the difference between MB and EEI insurance?

MB covers mechanical and electrical plant: motors, compressors, generators, production machinery. EEI covers electronic equipment: servers, PLCs, CNC controllers (the electronic part), UPS systems, data centre equipment. The distinction matters because electronic equipment fails differently (component-level failure, static discharge, data corruption) and requires different underwriting.

How is the MB sum insured calculated?

The sum insured should be the replacement value as new of each item of machinery. This means the cost to replace the machine with a new equivalent model, including freight, customs duty, and installation. Do not use book value or market value, as these will leave you underinsured and trigger the average clause.

Can I buy MLOP without MB?

No. MLOP is always written as an add-on to the MB policy. The MLOP trigger event must be an MB-insured loss. You cannot buy standalone MLOP coverage. Similarly, if your MB claim is denied (for example, due to gradual deterioration), the corresponding MLOP claim is also denied.

How long does a typical MB claim take to settle?

Most MB claims settle within 4-8 weeks of the loss adjuster's final report. The timeline depends on the complexity of the failure, the availability of repair quotations, and whether the cause of loss is disputed. Simple motor burnout claims with clear documentation can settle in 3-4 weeks. Complex failures involving root cause analysis may take 8-12 weeks.

What if my machinery is more than 20 years old?

Older machinery can still be insured, but underwriters may apply age-related conditions. These include higher deductibles, betterment clauses (where you pay the improvement component if old parts are replaced with newer technology), or exclusion of specific high-wear components. A strong maintenance record helps overcome age concerns.

Does MB cover the cost of upgrading to a newer model?

MB covers repair or replacement on a like-for-like basis. If the exact model is no longer available and you must upgrade, the insurer pays the cost of the nearest equivalent replacement. Any additional cost for upgrading beyond equivalent specification is your responsibility. The betterment clause addresses this.

What is the typical deductible for MB claims?

Standard MB deductibles in the Malaysian market range from RM5,000 to RM50,000 per occurrence, depending on the total sum insured and risk profile. Power generation equipment typically has higher deductibles (RM25,000-100,000). Choosing a higher deductible reduces your premium but means you absorb more of each loss.

How does MB insurance work with manufacturer warranties?

MB insurance is not a substitute for warranties, and warranties are not a substitute for MB. Warranties typically cover defects for 1-2 years after purchase. MB covers sudden and unforeseen breakdown throughout the policy period, including operator error and external power surges that warranties don't cover. After the warranty expires, MB becomes your only protection against internal equipment failure.

Foundation Conclusion

Your fire and IAR policies protect your factory against external events. But the most frequent and often most expensive equipment losses come from within: a motor burning out, a bearing seizing, a turbine blade failing. MB insurance covers those internal faults. MLOP covers the revenue you lose during repair.

Together, MB and MLOP complete your factory's engineering insurance programme. Without them, you're carrying the full cost of your most likely equipment failure scenario.
