Square D Load-Center Circuit Breakers

Match these circuit breakers to Square D breaker boxes or panel boards of the same manufacturer series. Because they are thermal-magnetic, these breakers trip two different ways. They either trip when heat is generated by sustained low-level overload current or quickly when the magnetic coil senses a high-current short circuit.

DIN-Rail Mount Equipment Circuit Breakers


Auxiliary Contact	Distribution Bar	Distribution Bar Terminal Cover

Distribution Bar End Cover	Shunt Trip	Extension Terminal

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.

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

B Trip

Poles—Toggle-Switch

Style

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.

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

D Trip

Poles—Toggle-Switch

Style

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.

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

Siemens Load-Center Circuit Breakers

Poles—Toggle-Switch

Style

Use with Siemens EQ series breaker boxes. Because they are thermal-magnetic, these circuit breakers trip two different ways. They either trip when heat is generated slowly by consistent low-level overload current or quickly when the magnetic coil senses a high-current short circuit.

UL 489—These circuit breakers meet UL 489 requirements for branch circuit protection, so they protect downstream equipment and wiring from overloads and short circuits.

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

DIN-Rail Mount Branch Circuit Breakers


Extension Terminal	Distribution Bar Terminal Cover	Shunt Trip

Auxiliary Contact	Distribution Bar

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.

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.

Cutler-Hammer Load-Center Circuit Breakers

Poles—Toggle-Switch

Style

Install these circuit breakers into Cutler-Hammer CH series breaker boxes. Because these circuit breakers are thermal-magnetic, they trip two different ways. They either trip when heat is generated slowly by consistent low-level overload current or quickly when the magnetic coil senses a high-current short circuit.

UL 489—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.

High-Temperature Panel-Mount Circuit Breakers

Poles—Toggle-Switch

Style

Unlike breakers that trip thermally, these breakers have a hydraulic-magnetic trip mechanism, so they aren’t affected by changes in temperature. Instead, these circuit breakers trip when they hydraulically sense consistent low-level overload current, or they trip quickly when the magnetic coil senses a high-current short circuit. Use the threaded holes on the face to install them through panels, enclosure covers, or walls to keep them close to the equipment they protect.

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

DIN-Rail Mount Ground Fault Circuit Protectors

2 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.

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. 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.
