The 201-100/200-DPDT series is an 11-pin octal base, plug-in voltage monitor designed to protect three-phase motors regardless of size. The 201-100-DPDT is used on 95–120 V ac, 50/60 Hz motors to prevent damage caused by low voltage. The 201-200-DPDT is used on 190–240 V ac, 50/60 Hz motors to prevent damage caused by incoming voltage problems. These monitors feature two isolated sets of contacts that are ideal for use with two control circuits with different voltages. The unique microcontroller-based voltage and voltage-sensing circuit constantly monitors the voltage to detect harmful power line conditions. When a harmful condition is detected, the MotorSaver deactivates its output relay after a specified trip delay. The output relays reactivate after power line conditions return to an acceptable level and a specified amount of time has elapsed (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.
Notes:
Must use Model OT11PC socket for UL Rating.
Manufacturer’s recommended screw terminal torque for the RB series and OT series octal sockets is 12 in.-lbs.
