Square D Secondary Circuit Breaker Boxes

Connect these boxes to a main box—they do not have a main circuit breaker switch. They are single-phase, 3-wire, and can be mounted for top or bottom feed conduit connections. Also known as load centers.

NEMA 1 rated boxes are for indoor use.

NEMA 3R rated boxes are for outdoor use.

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

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.

High-Power Circuit Breakers

Protect an area of a facility that has high-powered equipment. These circuit breakers are also known as molded case circuit breakers. They meet UL 489 requirements for branch circuit protection. Because these breakers are thermal-magnetic, they 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. A switch lets you adjust when these breakers magnetically trip, so you don't need to replace them as your application changes. These breakers have internal accessory slots to fit shunt trips, auxiliary contacts, and undervoltage trips, saving space in your setup.

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

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. 30A to 250A breakers can only have one shunt trip or undervoltage trip installed. 400A to 600A breakers can accommodate one shunt trip and one undervoltage trip at the same time.

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. Multiple auxiliary contacts can be used within one circuit breaker and can be placed in any of the accessory slots.

Undervoltage trips protect equipment from operating with less than their intended voltage by tripping a circuit breaker when the supply voltage drops below a set level. 30A to 250A breakers can only have one shunt trip or undervoltage trip installed. 400A to 600A breakers can accommodate one shunt trip and one undervoltage trip at the same time.

Install handles on the front cover of an electrical cabinet to turn these breakers on, off, or reset them without having to open the cabinet. Yet, these handles won’t prevent you from opening the electrical cabinet normally. You can also lock the handles in the on or off position with a padlock (not included) to prevent unauthorized changes to the circuit breaker.
