DIN-Rail Mount Equipment Circuit Breakers

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. 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.

Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.

B-trip circuit breakers are best for protecting sensitive equipment, such as programmable logic controllers (PLCs) and sensors, which could be damaged by a spike in current. These circuit breakers will trip if a rush of current reaches 3 to 5 times their rated current.

C-trip circuit breakers are the most common. They’re best for applications such as lighting and control panels, where equipment startup causes a moderate spike in current. They won’t trip until a rush of current reaches 5 to 10 times their rated current.

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. 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. For example, use them with a smoke detector to shut off power to a system in the event of a fire.

Auxiliary contacts send a signal to other equipment when the circuit trips. They can activate a warning light, initiate a shutdown, or start a backup power source.

Distribution bars simplify wiring by powering multiple adjacent circuit breakers without needing separate wires for each one. This cuts down on assembly time and space. Cut them to the number of terminals that you need.

Extension terminals raise the wire connection point above distribution bars for easy access to connect power to a set of circuit breakers.

Distribution bar end covers seal the live ends of distribution bars to prevent injury and damage.

Distribution bar terminal covers shield unused, live terminals on distribution bars to prevent injury and damage.
