Littelfuse 201A-AU-OT Monitor R-407C For high-precision applicationsThe Littelfuse 201A AU OT is a heavy duty, 8 pin 3 phase plug in voltage monitor engineered to protect motors from volatile line conditions. This auto ranging motor protection relay operates seamlessly across 190 480 VAC, eliminating the need for manual range selection between 200V and 400V systems. As a micro controller based unit, it provides precise sensing to mitigate phase loss, voltage unbalance, and phase reversal before damage occurs to the
