Advanced motor protection relays
What is an advanced motor protection relay? These are electronic devices providing additional protections, to the mandatory protections from overloads and short-circuits. As so they are always combined with motor protection circuit breakers, and configured to protect against several damageable events among supply phase failure, slight overload, locked or jammed rotor, protracted starting time, jogging or inching, under- or overvoltage, reversed phases, insulation and ground faults, underloaded motor, etc.
Like the motor protection overload relays, in case of such a fault, they deliver a powering-off instruction, either to the contactor, to the motor protection circuit-breaker, or merely a notification to the operator, or the automatic control of the industrial process.
