ANLY 3 Phase Sequence Voltage Relay APR-3S, 208~440V

The ANLY 3 Phase Sequence Voltage Relay APR-3S monitors and protects three-phase electrical systems operating between 208V and 440V. This relay detects phase sequence errors, voltage imbalances, and phase loss—critical faults that can damage motors and equipment. Ideal for industrial automation, pump stations, compressors, and machinery requiring phase protection. The APR-3S provides reliable fault detection with adjustable sensitivity settings, helping prevent costly downtime and equipment failure. Compact DIN-rail design fits standard control panels. Simple wiring and clear status indicators make installation and troubleshooting straightforward. Essential for any three-phase system where equipment protection and operational continuity matter.
