We at Concord offer a comprehensive range of Motor Protection Relays to protect your motor from burn out due to frequent and common problems including over loading, single phasing etc. The EOCR are electronic solid state or MCU (Microprocessor based Motor Protection Relays with multiple protections including over loading. Single phasing, reverse phase, phase unbalanced, locked rotor, ground fault, short circuit and undercurrent to protect your motors from premature failures even in extreme circumstances. The EOCR-operates on the basis of current sending principle with inbuilt current transformers which not only sense the current but also protects the motor. With a provision for independent adjustment of D- Time ( Starting Delay Time) and O- Time ( Operating Time) with definite and /or inverse type characteristics with wide current adjustment range. The EOCR is well equipped to guard your motor from failures. The EOCR is widely used and accepted all over by major users in all segments of the industry including automobile, Steel, Chemical, Petrochemical, Machinery and Paper etc.
