These relays are used for bus differential protection in conjunction with Linear Couplers, which are "air coil" mutual reactors.
Linear coupler relays for current less than 200MA
The type LC-2 relay provides protection for station busses where the DC component of short circuit current has a long time constant and causes saturation in current transformers of conventional design.
