Phase monitoring relays provide protection against premature equipment failure caused by faults in a 3-phase system. These 10A-rated relays, with LED indicator(s), are compatible with Wye or Delta systems and are available in a range of voltage inputs. The 8-pin socket required for these relays can be panel or 35mm DIN rail mounted.
Phase monitor relays provide protection against premature equipment failure caused by voltage faults on 3-phase systems. ProSense® phase monitor relays are compatible with typical Wye or Delta systems. Phase monitor relays protect against single phasing regardless of any regenerative voltages.
