Magnetic circuit breakers

These hydraulic/magnetic circuit breakers don’t rely on a temperature change to activate the trip mechanism, so ambient temperature and sympathetic heating have no effect on them. The circuit breakers don’t derate or deteriorate over time and can be used in any application from -40°C to 60°C. They come in a variety of frame sizes and types with current ratings as high as 100A. Short circuit capacities range from 500A to 10,000A at voltages as high as 240VAC/125VDC.
