8. Wiring the shunt coil MZ203 (Shunt Trip function)

The shunt coil - 230/415 V AC - HAGER MZ203 is an additional, non-compulsory safety mechanism that complements the mandatory differential
switch + circuit breaker pairing, in order to ensure the complete electrical protection of your charging station. It is implemented to cut the power to
the charging station in the event that the contactor of the T2/T2S socket becomes stuck.
The shunt coil must be present in order to obtain ZE Ready certification.
It couples to the circuit breaker, enabling it to be tripped remotely.
