Description
EVS800-1600 series low-voltage vacuum contactors are high-current extended series of EVS160-630 heavy-duty low-voltage vacuum contactors, which have the advantages of large making and breaking capacity, long electrical and mechanical life, and high reliability under harsh conditions. Rated working voltage 1140V or 2000V, rated current: 800A, 1000A, 1250A, 1600A. Can be multi-level combination.
EVS (800-1600) series vacuum contactors are single-pole structural units, which can be composed of n-pole vacuum contactors according to requirements. Its operating mechanism is electromagnetic holding type, DC magnetic system. When AC control power is used, the wire package is fed through a rectifier. It is suitable for electrical control occasions requiring high current control under the AC-1 and AC-2 use categories.
