SLU Phase Monitor Relays

ATC Diversified Electronics SLU Phase Monitor Relays offer cost-effective protection against premature equipment failure caused by voltage faults on 3-Phase systems (Wye or Delta). These SLU relays feature the 100 and 600 series phase monitors. The single SLU 100 series phase monitoring relays can be adjusted for the imbalance percentage, voltage, and time delay requirements to protect from single phasing. This single phasing can be regardless of any regenerative voltages or unbalanced voltages. The WYE and DELTA systems are monitored, and connections to neutral are not required in WYE systems. These SLU 100 series monitor relays operate at 240V switching voltage, a 10A contact current rating, and a 32°F to 131°F operating temperature range.
