Littelfuse PGR-6100 Ground-Fault and Insulation Relay Provides Exceptional Motor Protection
The PGR-6100 monitor combines the features of a ground-fault protection relay and insulation monitor into one unit. The monitor can detect a motor ground fault whether the motor is running (online mode) or stopped (offline mode). 通过在电机通电和未通电时监控绝缘电阻和接地故障电流来提供接地故障保护。 The PGR-6100 features two separate analog outputs for optional current and ohm meters and two separate alarm relays. The unit operates on one- or three-phase solidly grounded, resistance grounded, and ungrounded systems up to 6 kV. Selectable fail-safe or non-fail safe operating modes allow connections to shunt or undervoltage breaker coils. The PGR-6100 is unique in that it has predictive as well as protective capabilities.
