Circuit breakers protect wiring and equipment by cutting power when there is an overload or short circuit. Electricians, contractors and building owners use them in homes, offices, commercial spaces and industrial panels. This collection includes plug-in and bolt-on breakers, miniature circuit breakers (MCBs), molded case breakers (MCCBs), residual current breakers (RCCBs), motor protection and air circuit breakers from Chint, Royu, Sassin and Omni, plus circuit breaker finders.
How to choose a circuit breaker
- Type: plug-in and bolt-on breakers fit residential panel boards. MCBs mount on DIN rails in modern consumer units. MCCBs and air circuit breakers protect main feeders and larger loads.
- Ampere rating and poles: match the rating to the wire size and load, and use 1-pole, 2-pole or 3-pole to suit the circuit. 3-pole breakers are for three-phase supply.
- Breaking capacity (kA): this is the fault current a breaker can safely interrupt, such as 4.5kA, 6kA or 10kA for MCBs.
- Earth leakage protection: an RCCB trips when current leaks to ground, adding protection against electric shock.

Find the right breaker
A breaker finder such as the Klein ET300 or Cem CT-230 shows which breaker feeds an outlet before you work on it. Breaker sizing and panel work should be done by a licensed electrician. See more electrical tools, clamp meters and multimeters and cable and wire.
