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.

Panel-Mount Equipment Circuit Breakers
Mount these breakers, also known as supplemental protectors, through panels downstream from a branch circuit breaker to protect a single piece of equipment. They are rated UL1077 for protection against overloads and short circuits. These breakers can also be used as on/off switches. All are thermal, so they use the heat generated in overcurrent situations to trip the breaker.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
Covers for rocker style breakers (sold separately) provide IP54 protection against limited dust and splashed water.
Covers for push-button style breakers (sold separately) provide IP65 protection against water projected from a nozzle.

Harsh-Environment Circuit Breakers
Built to resist vibration and corrosion in harsh environments, these circuit breakers protect against overload and short circuits in low-voltage automotive and other electronic applications. All are thermal, so they use the heat generated in overcurrent situations to trip the breaker.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
Push-pull button and lever style breakers can be used as an on/off switch.
Place UL1077 rated breakers downstream from a branch circuit breaker to protect a single piece of equipment. They are also known as supplemental protectors.

Blade-Style Circuit Breakers
Protect against overload and short circuits in low-voltage automotive and other electronic applications. These circuit breakers can replace type ATC, AF, ATO, and 257 blade-style fuses. They are thermal, so they trip when heat is generated by overload current.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
Manual reset breakers require you to push a button after they trip.
Place UL1077 rated breakers downstream from a branch circuit breaker to protect a single piece of equipment from overloads and short circuits. They are also known as supplemental protectors.
