RS PRO Voltage Monitoring Relay With SPDT Contacts, 1 Phase, Overvoltage, Undervoltage


Use this monitoring relay from RS PRO to trip a circuit breaker in the event of undervoltage or overvoltage. You can adjust the minimum and maximum levels within a range of 50 to 500 V, making it easy to protect a range of equipment from damage.
To prevent momentary dips in voltage from tripping the circuit breaker, you can add a time delay of between 0.1 and 30 seconds. For ease of use, the relay has a green LED light that clearly indicates the supply status.
