Crompton 252-PTUU-TBX-DB-T1-EB 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-adjustableœover 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 adjustableœunder 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.

• Phase Loss, Reversal or Sequence
• Under and Over Current or Voltage Protection
