Product Description
SG1(WG) series load isolation switch
SGR1(WGR)series fuse dis-connector switch
General
SG1series load isolation switch is an updating product developed by Sahmataer .
The product derived series includes the cabinet external operation series, rear panel connection series, switch-disconnector-fuse series, automatic transfer load isolation switch series and so on. It is widely used for the power transmission and distribution power supply system and automatic system in the industries such as the construction, electric power and chemical industry,etc.
Applicable range
SG1 series load isolation switch is suitable for the distribution or motor network of AC50Hz rated current 100A -1600A (product of 1000A above is only for electric isolation ), rated insulation voltage 800V, rated working voltage up to and including 690V, DC rated working voltage up to and including 440V, to infrequently make and break the circuit and isolate the circuit.
SGR1 series switch-disconnector-fuse is suitable for the distribution or motor network of AC50Hz, rated current 100A~630A, rated working voltage up to and including 400V, to distribute the energy, under normal conditions, it can be used for infrequently making and breaking the circuit and performing the short-circuit protection and isolation of line and equipment.
