Description

General

Applications

Used in air conditioning units,elevator machine room,pumps,fans and other motor control applications,as protection of over-volltage.under voltage,phase failure,phase sequence and phase unbalance.When the power supply is abnormal,turn off power supply to protect the equipment.
