Bolt-On Miniature Circuit Breakers

Bolt-On Miniature Circuit Breakers

Mechanically attach these bolt-on miniature circuit breakers (MCB) to a circuit using fasteners. Circuit breakers protect electrical equipment from overload and shorts. They are commonly used in power supplies, motors, lighting, and appliances because their compact size requires less space in small enclosures. All circuit breakers must be used with a compatible panelboard or load center.

QOB Series

Provide AC and DC switching and protect against overcurrents in NQOD panelboards using these thermal-magnetic breakers. A trip-indication strip provides visual confirmation that the breaker has tripped. For multipole breakers, the mechanism trips when any of the poles encounters an overcurrent.

EDB Series

EBD equipment-protection circuit breakers have a thermal-magnetic design to protect against ground faults in a variety of instruments, including well pumps, and equipment used in water and wastewater, pharmaceutical, and chemical industries. They are compatible with NF breaker panelboards and interiors. Each breaker occupies two spaces within the panelboard.
