Resolution:
An insulated case circuit breaker is a molded case circuit breaker with an integral 2 step stored energy mechanism. They have the functionality of an iron frame breaker or a low voltage power breaker with a molded plastic instead of an iron frame.
Examples:
Masterpact MTZ, NW, NT breakers are molded case breakers, but are considered to be insulated case breakers due to the inclusion of the 2 step stored energy mechanism (charging handle).
Powerpact B, H, J, L, M, P, and R breakers are molded case breakers.
