main feature:
The primary circuit of the VJFC vacuum contactor-fuse combination electrical appliance adopts a solid sealed pole structure, which has good external insulation performance, and the vacuum sealed contactor solid sealed pole is completely maintenance-free throughout the entire life cycle. The fuse module also adopts the insulating mounting seat cast by epoxy resin APG process, which improves the insulation performance of the fuse and its support. The fuse can be installed into the fuse insulation tube from the contact end, and it is very convenient and quick to disassemble and replace.
VJFC vacuum contactor-fuse combination electrical appliance adopts monostable permanent magnet mechanism or electromagnetic mechanism. The mechanism coil has low steady-state starting ampere-turn, low long-term operation power consumption value, monostable permanent magnet mechanism has simple structure and the number of parts Reduced, more reliable, mechanical life, can be operated frequently. The mechanical life of the product is up to 300,000, and the electrical life is up to 250,000 times, which satisfies all kinds of frequent start control places.
