Machinery Breakdown
Chubb Commercial Insurance

Chubb is ranked by A.M. Best as the fourth largest underwriter of Machinery Breakdown insurance in the United States. Due to technological advances, companies are finding that machinery breakdown insurance is an essential component of any well-rounded insurance program.

Consider the unexpected occurrences that can damage equipment and cause expensive production delays or interrupt cash flow. Steam explosion, machinery breakdown and electric arcing are not insured in a standard "all-risk" property policy. Machinery Breakdown insurance from Chubb protects for:

  • Losses due to steam explosion, mechanical breakdown or electric arcing to property you own or operate
  • Liability for covered losses to property of others in your care, custody or control
  • Repair or replacement costs for damaged property
  • Legal expense incurred for defense against a claim or suit alleging liability under the policy

Customer Profile

Chubb’s Machinery Breakdown policy was designed with many industries in mind, including:

  • Commercial and Residential Real Estate
  • Communications and Broadcasting
  • Electronics
  • Equipment Manufacturing
  • Food Processing
  • Hospitals and Nursing Homes
  • Hotels and Motels
  • Light Metalworkers
  • Municipalities
  • Museums and Cultural Institutions
  • Plastics Manufacturing
  • Publishing
  • Schools and Universities
  • Textile and Apparel Manufacturing


The Choice Is Yours

To meet the varied needs of today’s businesses, Chubb offers the option of monoline or package formats:

Package – Chubb’s renowned Customarq Classic property policy automatically includes the three machinery breakdown perils. Our “one policy, one limit, one deductible” approach helps eliminate the gaps that can exist when a company has two policies with two carriers.

Monoline – Machinery Breakdown insurance can be purchased on a stand-alone basis when Chubb is not providing the property policy. This ISO-based policy provides insurance for direct physical loss or damage.

Machinery Breakdown losses can go beyond the repair or replacement cost of damaged equipment. We can enhance our Machinery Breakdown policy to include indirect losses that result from a breakdown including:

  • Business Interruption
  • Extra Expense
  • Spoilage
  • Ammonia Contamination
  • Utility Interruption

Why does a company need Chubb’s Machinery Breakdown policy? Consider the following scenarios:

On start-up, a crack develops in an aluminum extrusion press of a metalworking operation, halting production for 30 days. The total property and business income loss is $850,000.

Voltage spikes from a utility supplier causes severe electrical damage in a water treatment facility’s main transformer. The cost for the transformer replacement, as well as a temporary transformer rental, exceeds $425,000.

A high-rise apartment complex is heated by a large steam boiler. A safety relief valve fails and creates excessive pressure that causes an explosion. The cost of the boiler replacement, and the surrounding building damage, totals $350,000.

Don't take chances - protect your business with Chubb's Machinery Breakdown insurance.
