We are offering protection relay. Electric motors are crucial component in virtually every industrial automation application or environment. Therefore optimizing their performance and reliability can play a major role in reducing costs and improving overall plant efficiency. Electric motors fail and about half of them fail because of overheating through overload, phase failure or insulation breakdown. There are wide ranges of motors and motor characteristics in existence, because of numerous duties for which they are used and all of them need protection. Fortunately, the more fundamental problems affecting the choice of protection are independent on the type of motor and the type of load to which it is connected. Motor characteristics must be carefully considered when applying protection. It is emphasized because it applies more to motor than other items of power system plant. Protection of motor exists in any form, a variety of designs & either packaged individually or in different combinations. The fundamental and basic aim should be permit the motor to operate up to, but not to exceed its thermal and mechanical limits for overloads and abnormal operation conditions and to provide maximum sensitivity to faults.
Current Sensing SPP

This is a Current Sensing SPP, senses the current from the two phases and if current in any one of the three phases is absent, it operates the relay.This is perfectly suitable for the protection of the three phase motor.It Automatically resets when the fault condition is gone. LED Indicator for Power & Trip Auxiliary Supply : 230 VAC +/- 10% Input from 3 CTs of secondary rating 5A from each Phase Current Sensing operation Reset switch is provided to reset after tripping Output relay contact rating : 5A at 230V AC Field proven design Enclosure : Din Rail Mounting Size : 60 X 70 X 110 mm
