Monitoring relay 17.5mm wide, over / under voltage, phase sequence

Protects motors and other equipment against unstable voltages in the power supply system. Ensures protection of motors and other equipment by detecting overvoltages, undervoltages, phase sequence, and phase loss for three-phase power supplies. Phase loss detection while the motor is running Wide application of 3-phase 3-wire system (DIP switch change) Greater inverter noise resistance 17.5 mm width for reduced panel space Push-In Plus reducing wiring UL listed for easy shipping to North America Double insertion holes for cross-wiring (all terminals) Addition of models with transistor outputs for optimal contact reliability RoHS compliant
