DIN-rail three-phase motor protection relay for large pumps and motors, 525V three-phase motors (control supply 90–240V). Includes current transformer and resistor pack.

SKU: NIST-SUPRA-R3B Categories: , Brand:

The NIST SUPRA R3 is the protection relay for big three-phase pumps and motors, from small boreholes up to 545A. It mounts on a DIN rail in your own starter panel (DOL, soft starter or star-delta) and learns the normal running load of the motor.

  • Dry-run, overload, over- and under-voltage, phase failure, phase sequence and imbalance, too many starts
  • Pre-start insulation test checks the motor cable for earth faults before it starts
  • WiFi monitoring and control; optional RJ45 Ethernet add-on
  • Recovery timer up to 17 hours, 8 weekly timers, last 100 trips logged
  • Model R3_B: 525V three-phase motors (control supply 90–240V)
  • Includes current transformer and resistor pack
