The YCHGL Series is a robust Non Fused Disconnect Switch designed for reliable load breaking and safe isolation in electrical circuits. This heavy-duty isolation switch ensures secure power disconnection for maintenance and provides effective overload protection. It is built for durability in standard industrial environments and offers versatile mounting options to suit different panel designs.
The YCHGL series Non Fused Disconnect Switch (load-isolation switch) is designed to operate reliably within the following environmental conditions:
Altitude: ≤ 2000m
Ambient temperature range: -5℃ to +40℃
Relative humidity: ≤ 95%
Must be installed in a dry environment, free from explosive gases, rain, or snow.
If the isolation switch is intended for use in conditions outside the standard temperature range (above +40℃ or below -5℃), please inform the manufacturer for customized support.
