These circuit breakers meet UL 1077 requirements for supplemental circuit protection and are designed for use downstream of a branch circuit breaker. Use them with small transformers, lighting, and control circuits. All are thermal/magnetic—breakers trip when heat is generated by sustained, low-level overload current, but will trip quickly when the magnetic field in the coil senses a high-current short circuit. Mount directly to DIN rail.

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

Alarm (sold separately) sends an audible signal when the breaker is tripped.

Install these circuit breakers into Cutler-Hammer CH series breaker boxes. They meet UL 489 requirements for branch circuit protection. All are thermal/magnetic—breakers trip when heat is generated by sustained, low-level overload current, but will trip quickly when the magnetic field in the 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.

These magnetic circuit breakers are unaffected by temperature changes and trip when the magnetic field in the coil increases from current overload, so they are suitable for high-temperature environments.

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

Small enough to fit in tight spaces, these UL 489-rated circuit breakers provide branch circuit protection. They 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.

Replace any Edison-base fuse with these resettable circuit breakers.

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

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. 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.

These circuit breakers resist vibration better than standard low-voltage DC circuit breakers. They protect against overload and short circuits in low-voltage automotive and other electronic applications. Use them to replace type ATC, AT, ATO, and 257 blade-style fuses. 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.

In addition to protecting equipment, these circuit breakers can be used as on/off switches. Able to handle high inrush current found in motor start-ups. They meet UL 1077 requirements for supplemental circuit protection and are designed for use downstream of a branch circuit breaker. 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.

These magnetic circuit breakers are unaffected by temperature changes so they are suitable for high-temperature environments. They trip when the magnetic field in the coil increases from current overload.

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

Hardwire one of these converters to an extension cord to keep personnel safe from electric shock.

Converters with manual GFCI reset prevent unexpected start-up.

Keep personnel safe from electric shock with these cords. The industry desgination is SJTW, so the insulation resists water.

Cords with manual GFCI reset prevent unexpected start-up.

Cord with a power-indicating light have a light on the socket that illuminates when the cord has power.

Keep personnel safe from electric shock with these cords. Give the connectors a quarter turn to lock in place; they remain secure in high-vibration applications. All have a manual GFCI reset that prevents unexpected equipment start-up. The industry designation is SJTW, so the insulation resists water.

Keep personnel safe from electric shock with ground fault protection. These outlet strips have a manual reset to prevent equipment from starting up unexpectedly after ground is established.

Flip-down covers protect outlets from dust when not in use.

Suitable for use outdoors, these receptacles can be used in wet and damp environments. They keep personnel safe from electric shock by adding ground fault protection. Internal shutters prevent the insertion of foreign objects and accidental contact with power. The housing is impact-resistant plastic.
