MasterPact® NT circuit breakers are 70% smaller than the company’s MasterPact NW breaker, the company states. The redesigned contacts and the thermoset composite resin molded housing account for most of the saved space, according to the manufacturer. Three models are available. The company says its MasterPact NT ANSI C37/UL1066 low-voltage power circuit breaker 800A frame offers short-time withstand ratings of up to 42,000A and interrupting ratings of up to 50,000A. The MasterPact NT UL489 insulated case circuit breaker 800 and 1200A frames offer short-time withstand ratings up to 35,000A and interrupting ratings up to 100,000A. The MasterPact NT IEC 60947-2 800, 1200, and 1600A frames offer short-time withstand ratings up to 42,000 A, and interrupting ratings up to 150,000 A, the company says.
