Hydraulic magnetic circuit breaker unipolar (HM3)

This single-pole hydraulic magnetic circuit breaker complies with standard EN 60934 and meets standard NF F 62-001 (railway rolling stock). The rating possibilities range from 1 Amps up to 100 Amps. Use in direct current (DC) (90VDC) / (125VDC) or also in alternating current (AC) (up to 424 Volts 50/60 Hertz).

Hydro-magnetic circuit breakers have no thermal inertia after tripping, reclosing is effective immediately.

They also have no variation in caliber depending on ambient temperature. The nominal current of a HYDRO-MAGNETIC micro-circuit breaker does not vary whatever the ambient temperature.
