Crompton Protector Trip Relays

1 Crompton Protector Trip Relays Phase Loss, Reversal or Sequence Under and Over Current or Voltage Protection Load Detection Monitoring of Systems The Crompton Protectors provide continuous surveillance of the monitored circuit. When the current moves outside the set point limit, the relay operates. An illuminated LED indicates when the relay is energized. For 3 phase systems, the sequence of connection is not important. Standard overcurrent relays will energize on trip when the nominal input current plus the user adjustable over 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 undercurrent relays will de-energize on trip when the input current is below the nominal value minus the user adjustable under 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. 252-PHU On request, any product can be manufactured with the energize/de-energize functions reversed.

5 NK Technologies AC Current Switches If you control or monitor electric powered loads, you need current switches. Monitor fans, pumps, lights, and heaters for proper operation. Current switches give positive feedback that the load is operating and are much easier to install than alternatives like pressure switches, optical sensors, or zero speed switches. FF Case Style AS and ASX current switches combine a current sensor, signal conditioner, and limit alarm in a single package. AS1 series are well suited to automation systems of all kinds with their universal solid-state outputs and a wide frequency response. AS3 series have a high current output that works well with relay logic control schemes. ASX series combine the AS3 design with a built in adjustable time delay. All models feature high visibility LED indication and rugged construction. AC monitoring models are available in solid and split core cases.
