Voltage-Monitoring Relays

Littelfuse offers a variety of voltage monitoring relays that are designed to protect industrial equipment against voltage fault conditions. These single-phase and three-phase system relays provide highly accurate and precise voltage measurements that activate a response to abnormal operating conditions in order to prevent harmful damage to equipment. The voltage monitoring relays not only detect under-voltages and over-voltages, they also detect related issues such as phase imbalance, phase loss, and phase sequence.
