The 201-SP (201-xxx-SP) series is an 8-pin octal base, plug-in voltage monitor designed to protect single-phase motors regardless of their size. The 201-100-SP is used on 95–120 V ac, 50/60 Hz motors to prevent damage caused by low voltage. The 201-200-SP is used on 190–240 V ac, 50/60 Hz motors. The 201-200-SP-T-9 is a pin-for-pin replacement for a Time Mark® #260 series voltage monitor. High voltage protection is included in the 201-200-SP-T-9.

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’s output relay is deactivated after a specified trip delay. The output relay reactivates 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 OT08PC socket for UL Rating.
Manufacturer’s recommended screw terminal torque for the RB series and OT series octal sockets is 12 in.-lbs.

Features

  • Proprietary microcontroller-based circuitry
  • Fixed trip delay 4 seconds
  • Advanced LED diagnostics
  • Compact design for 8-pin, DIN-rail or surface mounted
