Working Mechanism

  • When a relay's coil voltage drops below a set threshold, an under-voltage relay comes into action.
  • Under-voltage relays shield loads from voltage drops that could cause brownouts and power outages.
  • When the voltage drops below a specific point, the relay contacts trip the circuit breaker.

Standards and Approvals

  • UL
