Crompton 252-PSFU-PQBX-C6 PROTECTOR TRIP RELAYS
The Crompton Protectors provide continuous surveillance of the monitored circuit. When the Current moves outside the set point limit, the relay operates. A red LED indicates when the relay is energized. For 3 phase systems, the sequence of connections is not important.
Standard over Current relays will energize on trip when the nominal input Current plus the user-adjustableover nominal value is exceeded, after the preset additional delay period if set. The relay will automatically reset to de-energize when the input Current is lowered past the setpoint minus the hysteresis (differential) value.
Standard under Current relays will de-energize on trip when the input Current is below the nominal value minus the user adjustableunder nominal value after the preset additional delay period if set. The relay will automatically reset to energize when the input Current is raised past the setpoint plus the hysteresis value.
