Insulated Case Circuit Breakers

Starting with the Basics! What is an Insulated Case Circuit Breaker?

Insulated Case Circuit Breakers are molded-case breakers using glass-reinforced insulating material, such as fiberglass for dielectric strength. In addition they have a push-to-open button, rotary/ratchet-operated low torque handles with independent spring-charged mechanism providing quick connect/quick disconnect operation.

CPS is your Insulated Case Circuit Breaker Specialist. With decades of experience and knowledge, Coastal Power Systems knows virtually every circuit breaker down to lock washer sizes and contact pressure ranges. With the help of our technicians and technical sales staff, CPS consults with you to determine whether your insulated case should be:

  • Repaired¬†
  • Reconditioned or Restored
  • Replaced
  • Upgraded to a New Retrofit or Retrofill

For all New and Reconditioned Circuit Breakers our certified technicians will perform primary injection testing, function testing of all devices and accessories, and an overall visual inspection prior to shipping. This ensures that your breaker is ready to plug and play upon arrival.

Each breaker will be shipped with a Power DB generated test report and secondary wiring diagram upon request. These may also be supplied to the customer electronically.

Insulated Case Applications

The Coastal Power Systems team is familiar with many systems that incorporate insulated case circuit breakers. We recognize that each system might have its own unique designs that allow it to work with the original circuit breakers installed. These systems include Ross Hill, NOV, GE (both Salem and Houston designs), GE Microdrill, IPs, Main-Tie-Main configurations, Communication and Zone Interlocking Scheme, Kirk Key Protected Schemas, and countless others.

CPS will be able to provide guidance and support for all of your Insulated Case circuit Breaker needs. This also includes providing information on any retrofit and retrofill opportunities available to upgrade your system. Call or email us for more information!
