Overview

FZN61-12 indoor high-voltage vacuum load switch is an indoor high-voltage vacuum isolation load switch (circuit breaker) with AC 50Hz and rated voltage of 12kv, which is developed by our company with its own technology. Its external design is special and novel, and its distribution equipment is simple in use structure, good in practical performance and smaller in cabinet width and volume. It can be used as the central network power supply equipment in distribution systems such as industrial and mining enterprises, residential quarters and schools.

Model meaning

Structural features of switch

FZN61-12 indoor high-voltage vacuum load switch is a modular design product, which integrates vacuum switch, disconnector, grounding switch, fuse holder and switch elements of operation panel, and can choose electric operation and auxiliary contacts.

The rotary disconnector has obvious fracture after switching off. The disconnector and grounding switch are linked, and the mechanical interlock with vacuum switch and cabinet door also meets the "five-prevention" interlock requirements of complete sets of high-voltage equipment. In particular, the interlocking function of "interlock" is also added in the operation hole of the panel, so that the whole switch has double interlocking functions of "five precautions" before and after.

The switch is small in size, and the width of the vacuum load switch is ≤299mm in the on-off state, and the rated current of the vacuum load switch (circuit breaker) is 1250A A.. The rated current of the combined electrical apparatus reaches 200A, which can protect the transformer of 200KVA.
