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.

Push-Button Style—Screw-On Mount
