Protect motors and other equipment from unstable voltages in the power supply system.
Detect overvoltages, undervoltages, voltage asymmetry, phase sequence, and phase loss for three-phase power supplies.
Phase loss detection while the motor is operating.
Global power supply support. (Changed with a switch.)
Greater resistance to inverter noise.
Width of 17.5 mm to reduce space required in panels.
Push-In Plus Terminal that reduce wiring work.
The use of cage clamps enables wiring with bare stranded wires.
Double-insertion holes for crossover wiring (all terminals).
UL listed for easy shipping to North America.
Certified for maritime standards (LR).
Models added with transistor outputs for superior contact reliability.
