Features

• Lineup includes a 17.5-mm slim, compact model.

• Greater resistance to inverter noise.

• Distinguishes between correct phases, phase sequence, and phase loss when power is turned ON.

• Supports phase loss detection when the motor is operating.

• Output status can be monitored using LED indicator.

• Ideal to prevent reverse operation of motors.
