Earth Leakage relay with dual outputs

We have introduced a variant of the ELRM44 that offers the user two relay outputs that operate simultaneously. The

relays are configured to energise when the ELR trips which provides the user with the option to use one contact to operate the

main switching device (i.e. shunt trip) and the other contact to be used for operating a lamp or buzzer for example.

Three models are available with limiting maximum trip settings of 3A, 10A and 30A.

This product is used in conjunction with an external Core Balance Current Transformer (CBCT) and will detect residual sinusoidal alternating and pulsating direct currents. An adjustable trip level and time delay allows the product to be set according to the type of installation to be protected. When the level of leakage current being monitored exceeds the set trip level, the unit will trip. Typically, the product is used in conjunction with an external switching device (i.e. contactor, shunt trip). An auxiliary supply is required to power this product.
