Circuit breakers are re-settable electrical safety devices that protect equipment and processes from damage caused by overload or short circuits. Their purpose is to interrupt current flow to protect downstream equipment and prevent the risk of fire.

• Molded case circuit breakers: for branch and feeder circuit protection of large loads, up to 1200 A
• Miniature circuit breakers: DIN-rail mountable for branch circuit protection, up to 63 A
• Miniature supplementary protectors: for additional protection and disconnecting means where branch circuit protection is already provided
• Electronic circuit breakers/protectors: provide single- or multi-circuit supplementary protection from a single device
• Mini supplementary protectors for terminal blocks: provide space-saving, terminal block style UL 1077 supplementary protection
