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

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.

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.

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

Mount these circuit breakers directly to DIN rail to protect equipment and wiring in an area of your facility from 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.

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.
