gfr1 series fuse switch disconnectors-凯发一触即发

application range
gfr1 series isolating switch fuse type load, the rated insulation voltage is 800 v, rated voltage 690 v, rated current 630 a, rated frequency 50 hz, in power distribution and motor with high short circuit current circuit, a power switch, isolating switch and emergency switch, and as circuit protection, but is generally not as open and close the single motor directly.this product performance indicators in line with the iec60947-3, gb14048.3 standards.
characteristics
1、both mounting base and encolosure of gfr1 series fuseswitcdisconnector are made of plastic and electronic prevention cage is installed on the switch. so the

gfr1 series fusewitch-disconnector is the feature with compact construction, light weight, reliability safety, easy to install and beautiful appearance.
2、gfr1 series fuse-switch-disconnector has micro-gap switch which used for the supply change-over of the indication of the switch breaking and closing.
3、rated duty: both contacts and socket bases of the switch are silver plated，so the switch could works in uninterrupted duty.normal service conditions；without micro-gap switch；with micro-gap switch；pole number；conventional thermal current；design code brand “securelucky”fuse-switch-disconnector
1、the altitude of the site of installation does not exceed 2000m；

2、the ambient air temperature dose not exceed  40℃ and the lower limit of the ambient air temperature is -5℃, meanwhile, its average over a periods of 24h

does not exceed  35℃；

3、the relative humidity of the air does not exceed 50% at a maximum temperature of 40℃. higher relative humidity may be permitted at lower temperature，e.g. 90% at  20℃.special measures may be necessary in cases of occasional condensation due to variations in temperature；
4、pollution degree: iii；
5、mounting classification：iii；
6、without notable shock and vibration.
