Επισκόπηση
The VIOX VRL22 is an electromagnetic, voltage-independent residual current circuit breaker with overcurrent protection. It combines residual-current, overload and short-circuit protection for AC 50/60 Hz circuits. Available configurations include Type AC, Type A, Type ASi, Type A G short-time-delayed and Type A S selective versions. The series covers 1P+N circuits at 230/240 V AC and 3P+N circuits at 400/415 V AC. It is intended for residential, commercial and light industrial distribution systems and may also be used for infrequent switching under normal operating conditions.
