KFINE DC Miniature Circuit Breaker KFB3-63Z

      The KFB3 Series Miniature Moulded Case Circuit Breakers feature a sleek, compact appearance, light weight, excellent and reliable performance, high breaking capacity, rapid tripping, and DIN rail mounting. The housing and components are made of high-flame-retardant and impact-resistant plastics, ensuring a long service life.

They are mainly used in circuits with AC 50Hz/60Hz, rated voltage 230/400V and rated current up to 125A, to provide overload and short-circuit protection for electrical lines. Under normal conditions, they can also be used for infrequent line switching, and serve as disconnectors to cut off circuits for line and equipment maintenance.
