Square D Load-Center Circuit Breakers

QO Series, 2 Pole

QOB Series, 2 Pole

Homeline Series, 2 Pole

Match these circuit breakers to Square D breaker boxes or panel boards of the same manufacturer series. They meet UL 489 requirements for branch circuit protection, so they protect downstream equipment and wiring from overloads and short circuits. 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.

Circuit breakers with ground fault sensitivity will trip if they detect a current leak above 6mA. This minimizes the risk of electric shock to workers and equipment.

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

High-Temperature Panel-Mount Circuit Breakers

2 Pole

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 is the maximum current that the circuit breaker can safely stop in the event of a short circuit.

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.

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 have 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.

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.

DIN-Rail Mount Ground Fault Circuit Protectors

2 Poles

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 meet strict UL 1053 standards for ground fault detecting devices. They will trip if they detect a current leak above 30mA. 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.

Breakthrough current is the maximum current that the circuit protector can safely stop in the event of a short circuit.
