Setting of the motor protection relay is based on the motor datasheets information and system configuration. • Datasheets are normally provided by motor manufacturer. • System configuration data can be obtained from single line diagram.
If one of those relays operates (which means that an output contact closes because the relay detects a level of distress in excess of its calibration or setting), it initiates tripping of circuit breakers or other protective devices which then isolates the defective system components. It may be convenient to think of the circuit breaker
