Circuit Breakers

Circuit Breakers are unaffected by temperature.

Hydraulic/Magnetic circuit breakers do not rely on change in temperature caused by increased current flow to activate trip mechanism. Unaffected by ambient temperature and sympathetic heating, products do not derate or deteriorate over time and can be used in any application from -40 to +140°F. Various frame sizes and types are available with current ratings to 100 A, and short circuit...
