GW28GS- Series Latching Selector Cam Switch With Current 20A/25A/32A/63A/125A

WHAT ARE GW28GS- SERIES CHANGEOVER SWITCHES ?

GW28GS series padlock type power switch is a derivative of TW26 series universal switches. It is mainly used as a power cutout switch that is required to be padlocked in the machine tool, and can be padlocked in the OFF position (i.e. "0" or "off" bit) and the ON position (i.e. "1" or "on"), so as to prevent miss operation and control the operation of unauthorized personnel. Besides, this product meets the required standards: GB14048.5-2001, IEC60947-3.

CHARACTERISTICS

• Convenient and Fast

• Safe and Reliable

• Economical and Environmentally Friendly

• Superior Efficiency

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.

PRODUCT CLASSIFICATION
