The Earth Leakage Relay ELR-A is a device which offers a wide possibility of regulation both for time and current. The housing of the ELR-A is DIN six module size (one module is 17.5mm) together with the 28mm built-in toroidal transformer. This design allows to optimize the size of the ELR and reduce the electromagnetic fields which normally are due when toroidal and ELR need to be wired to each other.
