Model 202 is an auto-ranging voltage monitor designed to protect three-phase motors regardless of size. It is used on 190-480 VAC, 50 to 60 Hz motors to prevent damage caused by single phasing, low voltage, high voltage, phase reversal, or voltage unbalance.

Installation Instructions

A unique microcontroller-based voltage and phase sensing circuit constantly monitors the three phase voltages to detect harmful power line conditions. When a harmful condition is detected, the MotorSaver's output relay is deactivated after a trip delay.

If you are looking for SymCom 202 Voltage Monitors, please call us on (800) 894 - 0412 or email us at we will do our best to help you find the 202 voltage monitor that you are looking for at the most competitive prices possible.

  • Compact design saves precious panel space.
  • 0.25" hole allows easy OEM mounting.
  • Diagnostic bicolor LED indicator light is green in normal conditions, red during trip conditions, blinking green while in restart delay mode and blinking red when reverse phased.
  • Universal range from 190-480 VAC 50/60 Hz provides the versatility needed to handle global applications.
  • Transient protected to meet IEC 1000-4-5,±4kv.
  • Detects single phase conditions regardless of regenerated voltages.

The output relay reactivates after power line conditions return to an acceptable level for the selected amount of time (Restart Delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.

Note: To obtain UL listing for the MS202, use insulated 1/4" UL recognized female quick connects.

Protects 3-Phase motors from:

  • Loss of any phase (single phasing)
  • High and low voltage
  • Voltage unbalance
  • Phase reversal

Weidmuller Timers

The Time Range is chosen by turning the rotary switch for the ON-time scale and OFF-time scale. The time scales are visible in the display to the left of the rotary switch in the following order: 0.1 s, 1 s, 0.1 m, 1 m, 0.1 h, 1 h. The rotary switches for the ON/OFF time adjustment and the option selector for the time scale can be locked with the locking key. This pen-style special tool

TURCK Sensors

The Universally Applicable magnetic field sensors operate extremely reliable, even in rough production environments. This is guaranteed through excellent EMC immunity, protection class IP67 as well as the especially safe installation method of the sensors. We placed great emphasis on practical functionality of the housings and solid mounting accessories. Magnetic field sensors thus withstand the rough
