Earth-leakage protection relay

ACDIN rail

Sigma leakage current protection relayis used together with LV circuit breaker, tripping coil and toroidal transformer in combination with leakage current protection. The connections that must be made when using the leakage current detection relay; Apply voltage 220V AC to the terminals 1-2. Connect the secondary terminals of the toroidal transformer to terminals 6-7. The supply voltage of the pickup coil is taken from terminal 13 and from the neutral point of the supply. Depending on demand, you can test and reset remotly using terminals 3-4-5.
