Products represents tripolar disconnectors with fuses with vertical or horizontal base (structure) for direct mounting on busbars. They are intended for inclusion, exclusion, disconnection and protection of low voltage cable lines and are accompanied by all the necessary documents. Their light construction, combined with the easy replacement of LV fuses and the high level of protection, make these products a practical and secure solution. Choosing between these two types of circuit breakers is determined by their specific characteristics, preferences of chief engineers or designers and, of course by the free space for usage, which youhave. Basic capacities that Zhejiang GRL Electric Co.,Ltd. offers are: 160А, 250А, 400А, 630А и 1000А.
