RCD type A, 3-phase + neutral, 25A 6 mA

ONESTO EV RCD, type A, 4-pole, 25 A, 30 mA, with 6 mA DC detection

The ONESTO EV RCD is designed to protect electric vehicle charging circuits. It combines the detection of type A residual currents with additional detection of smooth direct current (DC) residual current.

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

The 4-pole design: three phases and a neutral wire allows for use in a appropriately selected three-phase supply circuit for the charger.
