DIN-Rail Mount Equipment Circuit Breakers


Auxiliary Contact	Distribution Bar	Distribution Bar Terminal Cover

Distribution Bar End Cover	Shunt Trip	Extension Terminal

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. 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. Cut them to the number of terminals that you need.

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.

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

C Trip


1 Pole—Toggle-Switch Style	2 Poles—Toggle-Switch Style	3 Poles—Toggle-Switch Style

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.

UL 1077—They are rated UL 1077 for protection against overloads and short circuits.

DIN-Rail Mount Ground Fault Circuit Protectors


2 Poles—Toggle-Switch Style	4 Poles—Toggle-Switch Style

Add ground fault protection to a circuit to minimize the risk of electric shock to workers and equipment if there is a current leak. These protectors will trip if they detect a current leak above 30 mA. However, they do not protect against overloads. Pair them with a circuit breaker to fully protect a circuit. Commonly used in electrical enclosures, these protectors mount directly to DIN rail.

UL 1053—These protectors meet strict UL 1053 standards for ground fault detecting devices.

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

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.

Automatic Reset

Automatic reset breakers don’t require you to manually reset them after they trip, so they’re good for areas where the breaker isn’t easily accessed. These breakers reset once they cool. However, they will trip repeatedly if the overcurrent condition continues.

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

Manual Reset—Push-Button Style

Manual reset breakers require you to push a button after they trip.
