Westinghouse first made the SPB insulated case and then sold the line to Cutler
Hammer an Eaton Corporation subsidiary. These circuit breakers combine the best
of both worlds. Small, compact, and higher interrupting than similar air circuit
breakers. With solid state trip units for coordination not found in molded case
circuit breakers.

These units, known as insulated case circuit breakers, are found in more and more
industrial and commercial applications such as high rise buildings, hospitals,
offshore oil rigs, generators, and as a main disconnect for molded case distribution
