This residual current monitor will detect DC and AC residual currents in 50Hz/60Hz AC installations according to IEC62955
It's primarily intended for use in Electric Vehicle charging stations to disconnect the supply to the Electric Vehicle under a DC residual fault current condition.

The module can be directly connected to the SmartEVSE v3.
It will protect against DC (6mA) and AC (30mA) residual currents, and will signal to the SmartEVSE if a fault occurs.
The SmartEVSE will then immediately disconnect the contactor, display an error message on the screen, and wait for a user to reset the error.

When using this module, you don't need an expensive type B residual-current circuit breaker (RCB) in your mains distribution panel, but can use a normal type A.

• For use with single or 3 phase loads
• max 100A Single Phase or 40A 3 Phase
• ROHS compliant
• Complies with the DC protection requirements of IEC62955
• 3000A Surge Current Withstand
• 14mm Aperture

The residual current monitor comes with a matching cable that allows you to connect it to the SmartEVSE.
