TPR-6

Temperature Protection Relay

The TPR-6 Temperature Protection Relay is designed to protect electric motors, transformers and other systems from overheating. The TPR-6 has up to 14 temperature inputs that can be programmed to measure thermistors (PTC or NTC) and RTDs (Pt100).

 Protection Features: 

  • RTD / Thermistor with two levels for each input 
  • Thermistor PTC / NTC selection 
  • Over temperature Alarm and Trip to each input 
  • Continuous analog output signal 
  • External fault 1 and 2

Exact input can be assigned to any of the following items:

 

  • Alarm only - Relay A 
  • Trip only - Relay B 
  • Fan (Trip, Alarm)- Relay C
  • Trip/Alarm- Relay D
  • Enabling Auto Reset
