BROYCE CONTROL PHASE VOLTAGE & THERMISTOR 3PH RELAY 400VAC
SKU: 45PTR
*
S$179.12
  • Combined Three Phase and Thermistor Relay
  • Used in conjunction with PTC thermistors to DIN 44081
  • Three Phase voltage monitoring
  • Auxiliary supply
  • 2 x SPNO Relay outputs
  • 45mm wide, DIN Rail mount

The product offers temperature and three-phase voltage monitoring and provides a dedicated relay output for each.

> Temperature monitoring: PTC thermistors are connected externally and up to 6 can be used if required. The relay output is normally energised and de-energises when the measured resistance increases (due to a temperature increase) above a fixed set-point. The relay re-energises again when the temperature/measured resistance decreases below the “release” set-point.

> Three phase voltage monitoring: When all phases are present, sequence is correct and phase to phase voltage above the threshold voltage, the relay energises. The relay will de-energise if a phase is missing, sequence is not correct or voltage is below the threshold.
