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.
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.

DIN-Rail Mount Branch 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. They meet UL 489 requirements for branch circuit protection and are certified as current limiting, so they protect equipment by minimizing passing current during a short circuit. 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.
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.
Extension terminals raise the wire connection point above distribution bars for easy access to connect power to a set of circuit breakers.
Distribution bar terminal covers shield unused, live terminals on distribution bars to prevent injury and damage.
