Circuit breaker

Circuit breakers that provide reliable protection for conductors in hazardous areas
R. STAHL offers a variety of different circuit breakers designed for specific intended purposes in hazardous areas, each and every one of which provides outstanding protection against earth faults, overloading and short-circuiting. They capitalise on their ability to very effectively limit current to minimise the current load on the conductors in the event of a short circuit.

R. STAHL produces various types of circuit breaker, which protect your systems against earth faults, overloading and short-circuiting. They are designed for rated currents of 0.5-40 A and rated tripping currents of 10/30/100/300/500 mA, and can switch 6 or 10 kA. The 8523/8 series circuit breakers are equipped with a non-adjustable short-circuit tripping mechanism and an adjustable thermal overcurrent release up to 22.5 A. The 8562/5 series miniature circuit breakers open safely and selectively and, in the event of a short circuit, capitalise on their ability to very effectively limit current to minimise the current load on the conductors. The RCD/MCB trips in the event of residual currents and also performs the role of miniature circuit breaker. This two-in-one switch is a practical combination that reduces installation work and takes up less space than two separate switches.

  • Excellent current limiting capability in the event of a short circuit, low current load on the conductors, high selectivity
  • Circuit breaker with adjustable thermal overcurrent release
  • Space saving two-in-one RCD/MCB
