• To be used with ELR-B, ELR-3C and D30 relays.
• The transformer and relay assembly sensitivity is
• The transformer and relay assembly sensitivity is
fixed by the relay.
• The toroidal transformer CTD-1/28 is specifically
designed for DIN rail mountig.
Working principles: The toroidal transformer is
installed between the source and the load. The
system works on the current balance principle. In
a correct installation the vector sum of the
currents is zero and the relay will not trip.
installed between the source and the load. The
system works on the current balance principle. In
a correct installation the vector sum of the
currents is zero and the relay will not trip.
In case of an insulation fault on the circuit a
leakage current flows to earth. Now the vector
sum of the current passing through the
transformer is not zero, this inbalance is
detected by the transformer, which induces a
current in the secondary winding which is
connected to the relay.

If the fault level is higher than the selected
sensitivity, and when the trip time delay has
elapsed, the relay trips and actuates on the shunt
trip of a circuit breaker or the coil of a contactor
interrupting the supply to the load.

The dimensioning of the toroidal transformer
depends on the diameter of all active wires (not
earth conductors) put through the
transformers.
