Munro Startbox - Thermal Protection


Munro Startbox - Thermal Protection

This StartBox variation protects the pump motor from damage due to over amping while still performing all the basic functions the standard pump start relay does.

  • Provides the pump motor with thermal overload protection, even when the motor itself does not.
  • Auto-resets upon cool-down.
  • For use with single phase motors.
  • Reduced incoming amperage option available

CONSTRUCTION

  • Quick-connect terminals
  • UL listed relay
  • UL-50 Type 3R listed enclosure – approved for outdoor use, available in stainless steel or powder coated blue*

National electrical code (NEC) states all motors will be thermally protected from excessive “amperage draw.”
Motors 2 hp and under are supplied with thermal protection from the motor manufacturer. For motors over 2 hp, StartBox with thermal protection is recommended.
