* in the case of nominal load
The contacts are zero volt.
N/C fault indicating relay - the relay closes immediately after the power is switched on and opens
in the event of a fault.
N/O fault indicating relay, the relay closes in the event of a fault.
Use suitable interference suppression (e.g. RC glands) when connecting inductive loads.
