Phase Voltage and Thermistor
45PTR Combined Phase Sequence/Failure & Thermistor Relay
Separate Relay & LED operation for Three Phase Monitoring 'V' & Thermistor monitoring 'T'
The relay monitors the following:
Incorrect phase sequence/rotation
Threshold voltage 60% of 400Vac
Phase failure/loss
Phase under-voltage (0.6 x 400Vac)
Thermistor over-temperature
Thermistor open circuit
Thermistor short circuit
Output relay: 10A (Thermistor)
Output relay: 10A (3 Phase)
