Residual current circuit breaker type A, single-phase + neutral, 40A, 6 mA

ONESTO EV residual current circuit breaker, type A, 2-pole, 40 A, 30 mA, with 6 mA DC smooth current detection

The ONESTO EV residual current circuit breaker is designed to protect electric vehicle charging circuits. It combines the detection of type A differential currents with additional detection of smooth DC differential currents.

The device reacts to sinusoidal alternating differential currents and pulsating DC differential currents. The rated differential current is 30 mA, and the smooth DC current detection threshold is 6 mA.

The 2-pole design: phase and neutral wire allows for use in a suitably selected single-phase circuit supplying the charger.
