SymCom MotorSaver Model 202 3-Phase Voltage Monitors

SymCom MotorSaver 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. 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. 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.

Features:
  • 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.
Protects 3-Phase motors from:
  • Loss of any phase (single phasing)
  • High and low voltage
  • Voltage unbalance
  • Phase reversal
Standard Features:
  • UL and cUL recognized
  • 5 year warranty
  • Made in USA
  • Manual, 2-300 sec. variable restart delay
  • Mounts on panel surface

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
