WHAT ARE GW28 SERIES CHANGEOVER SWITCHES?

GW28 series, mainly used in AC 50Hz, rated voltage 380V and below, and rated current to 125A electrical lines as well, are used for manual infrequent switching or disconnecting circuit for control box conversion. They can also directly control three-phase asynchronous motors and be used for main command control and circuit measurement. The products are widely used to replace all kinds of transfer switches, and can be used as circuit control switches, test equipment switches, motor control switches and master switches, and welding machines with transfer switches, etc. Meet the standard : the main circuit conversion and direct control conversion switch meet GB14048.3-2001. The transfer switch for master control conforms to GB14048.5-2001.

CLASSIFICATION

By use :

  • Transfer switch for main circuit conversion
  • Transfer switch for direct control of motor
  • Transfer switch for direct command control and measurement

By mode of operation :

  • Locating type
  • Momentary type
  • Locating and momentary type

By contact system :

  • The locating type transfer switch has 1 to 12 layers (but only 8 layers in 63A).
  • The momentary type transfer switch has 1 to 3 layers.
  • The transfer switch for direct control of the motor mainly has 1~6 layers.

Note : 

① Zero line ground

② AC-23A, AC-3 and AC-4 rated power numerator represents 3 phase 3 poles, while their denominator represents 1 phase 2 poles. Besides, AC-2 is 3 phase 3 poles.

NORMAL WORKING CONDITIONS

  • The ambient air temperature : ≤ +40℃
  •  The average temperature within 24 hours :≤ +35℃
  • The lower limit of ambient air temperature : ≥ -25℃
  • The altitude of the installation site : ≤ 2000m
  • When the highest temperature reaches +40℃, the relative air humidity shouldn’t be more than 50%. Higher relative humidity is allowed in the relatively lower temperature, such as 90% humidity in 20℃. Special measures should be taken to deal with the condensation occasionally caused by the temperature change.

INSTALLATION CONDITIONS

  • The switches should be installed in the environment conditions of pollution level 3.
  • Please install these GW28 series according to the instructions provided by the factory.
