What is a k & d curve breaker?The ideal application is a circuit with a motor load. The K and D curve breakers are both designed for motor applications where ampacity rises quickly and momentarily during “start-up.” Both curves can “ride through” the momentary inrush of current and prevent nuisance tripping while providing protection to the circuit.
What is a D-trip circuit breaker?Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit. D-trip circuit breakers prevent nuisance tripping, so they are best for equipment that has a high spike in current at startup, such as transformers, power supplies, and heaters.
What is a supplemental circuit breaker?Also known as supplemental protectors, these circuit breakers mount directly to DIN rail downstream from a branch circuit breaker to protect a single piece of equipment. They are rated UL1077 for protection against overloads and short circuits. Because they are thermal- magnetic, these breakers trip two wa
