LC-1 linear coupler relays

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.
