Easily installed on poles and in substations, Eaton's Cooper Power series W-group three-phase, electronically controlled automatic circuit reclosers provide reliable, economic overcurrent protection. Available with vacuum or oil interruption, tripping is initiated by a series trip coil that releases the stored-energy trip mechanism when an overcurrent occurs. A closing solenoid supplies the energy for contact closing and also stores energy in the trip mechanism. Dual time-current characteristics permit coordination with other protective devices. A choice of four delayed characteristics allows flexibility in system coordination.
