Analogues by specifications
VA 47-125 PROXIMA EKF circuit breakers, thanks to their high breaking capacity of 15 kA, can be used instead of power circuit breakers. The switches have a housing width of 1.5 modules (27 mm) and are produced with rated currents up to 125 A. For reliable arc quenching, a double contact break and two arc chutes are used. Optimal conductivity is ensured by a silver-containing contact group.
