Technical FAQs 4

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.

Can a shunt trip a circuit breaker?

They will not trip unless a rush of current reaches 10 to 20 times their rated current. Shunt trips receive a signal from equipment to trip your circuit breaker in situations other than overload or short circuit conditions.

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 ways.

What is a ul 1077 breaker?

They are rated UL1077 for protection against overloads and short circuits. Because they are thermal- magnetic, these breakers trip two ways. They either trip when heat is generated slowly by consistent low-level overload current, or they trip quickly when the magnetic coil senses a high-current short circuit.
