Product Description

ZW43 12kv vacuum circuit breaker

ZW43-12/T630-20 type outdoor high voltage isolate vacuum switch is a new generation of high voltage electrical equipment developed by both home and overseas advanced technology. Each of the technical performance have reach the standard of GB3804 and IEC.

They are designed for the construction and reform of urban and rural grid. The bottom of the product has adopted stainless steel and galvanized carbon steel with ultraviolet-proof coating material, to make sure it’s normal outdoor operation. Each stainless steel component can ensure it’s durability, stability, water-proof and salt fog against ability.

It has characteristic of small size, light weight, good appearance, easy operation, strong breaking ability, long electrical life maintenance free and obvious fracture. It can adopt manual single-pole operation and also electric, distance operation.

Application:

1.This outdoor high voltage vacuum circuit breaker that the rated voltage of the three-phase ac 50HZ outdoor distribution equipment the rated current 630A~1250A, short-current 20KA.It mainly used for loading current, overcorrect and short current which use cut-off and close-open electricity system-
2. Suitable for industrial and mining establish company. The aim is to protect and control the system and easy to suitable the rural and some frequent operation place.
