Product review
Description
Function
Applications
Used in switchgear, air conditioning units, elevator machine room, pumps, fans and other motor control applications. With phase loss, overload protection.
Built-in microprocessor, current measurement accuracy≤ 2%. Konb setting, LED indicator shows working status. With phase failure, overload, unbalance, stall protection, four optional trip classes. No-load start, protection of any phase loss or overload. NO contact protection.
