Tips: Features of miniature circuit breaker

  • The rated short-circuit breaking capacity is high, and some rated current levels can reach more than 10KA.
  • Miniature circuit breaker has double wiring function, which can easily connect standard bus bar and flexible wire.
  • Mini circuit breaker is combined terminal block with finger protection, higher safety.
  • With energy storage mechanism operation, the contacts close quickly, which overcomes the adverse effects caused by the speed of manual operation of the handle, and improves the service life of the product.
  • A variety of accessories to choose from, and modular and flexible combination, user installation is very convenient.
  • The shell and some functional parts are made of high flame-retardant, high temperature resistant and impact resistant plastics.
  • High current limiting coefficient and economical price.
