      A voltage sensor relay from Grainger is an effective way to monitor current levels in a circuit. When voltages reach a certain level, the sensor relay acts like a contact point for reliable, steady operation that protects against phase loss, phase unbalance, phase reversal and undervoltage. Find 3-phase line monitors and other voltage sensors at Grainger.
