Insulated Case

Insulated Case breakers are similar to Molded Case in that they are completly enclosed in a housing made of insulating material. The housing is deigned with two halfs that can be seperated to perform repairs or add accessories. Insulated case breakers have ratings up to 6300A and are available as bolt-in or draw-out construction, as well as several interal accessories.


Every insulated case that leaves our facility is fully refurbished. In addition to NETA/ANSI testing specifications, we measure current, voltage, and timing for all motors, closing coils, UVR’s and shunt trips. This provides you unparalleled data collection and documentation.


If you do not find the breaker for your requiments in our inventory please email or call as we can build out the breaker accessories to your specific application. There is also inventory that has not been entered.
