EC Series Relays
The NewElec EC series of electronic motor protection relays will monitor the insulation integrity of protected motor windings and feeder cable cores to earth while the motor is standing. The main contactor is prevented from closing the circuit in which the insulation level to earth is below the permissible level. The selected Lock-out relay model determines the minimum value of insulation level.
The relay is typically used in areas where use of plant and equipment is of a seasonal nature, where motors are subjected to hosing down (i.e. Abattoirs), where high condensation occurs in standby equipment, and often in coastal areas.
