Type A residual current circuit-breakers detect pulsating direct current and alternating current. Our EV RCCB was specifically developed for use in charging stations for electric vehicles. The EV RCCBs detect smooth DC residual currents and safely trip at 6 mA DC. This protects upstream type A or F RCCBs and ensures maximum safety at your charging station. NA RCCBs allow you to connect push-buttons for the immediate shutdown of the power supply. This enables a fast and precise response in the event of an emergency. The integrated LED continuously displays the status of the emergency switching-off circuit. The HD design makes our RCCBs particularly resistant to harmful environmental influences and therefore suitable for harsh environments.

tripping not dependent on mains and auxiliary voltage, sensitive to AC residual currents and pulsating DC residual currents (type A) , supplementary function, dependent on the mains voltage, for detecting smooth DC residual currents and emergency switching off function, tripping threshold of 6 mA for smooth DC residual currents, LED display for when the supplementary function is active, No additional wiring overhead, compact design for all rated currents, high short-circuit resistance, double-sided two-tier terminals for large conductor cross-section and busbar, switch position indicator, viewing window for labels, multifunction switch toggle with three positions: "on", "off" and "tripped", Neutral conductor position left

quick fastening to mounting rail, any installation position, supply from any direction

These RCCBs are only designed for use in charging stations for electric vehicles, Not permitted for protecting systems in which electronic equipment may cause residual currents with frequencies not equal to 50 Hz. AC/DC sensitive residual current circuit-breakers of type B or B+ must be used in this case.
