VACUUM CIRCUIT BREAKER
630A/1250A/1600A/2000A/2500A/3150A/4000A
12kV/24kV/35kV

   ZN63(VS1) series vacuum circuit breaker is used for rated voltage isolator 12kV-35kV, 3-phase switch device, the indoor as grid equipment, industrial and miningenterprises, power equipment control and protection unit. Due to the specialadvantage, vacuum circuit breaker products suitable for the current requirementsrated frequent operation, or multiple open short-circuit current.By the integral layout structure, breakers used spring operation mechanism ismature, simple structure and reliable performance. The reasonable construction,make each points clear, functional units to decorate maintenance.
    ZN63(VS1) vacuum circuit breaker in the form of installed within theswitch can be fixed, also can be drawn. From 630A - 4000A rated current ratingfrom 20KA-31.5KA short-circuit current, real serialized form.

Core Features
Vacuum arc extinguishing technology
Adopting high-performance vacuum arc extinguishing chamber, strong breaking ability, no explosion risk, environmentally friendly and pollution-free.

The rated short-circuit breaking current can reach 20kA~31.5kA (depending on the model).

Modular design
The spring energy storage operating mechanism has a fast opening and closing speed and a mechanical lifespan of 10000 to 30000 times.

Can be equipped with manual or electric control (supporting remote automation operation).

safety protection 
Fully enclosed insulation structure, protection level IP3X, dustproof and moisture-proof.

Built in mechanical interlocking to prevent misoperation.

Standards
Compliant with international/domestic standards such as GB/T 1984 and IEC 62271-100.

Packaging & Shipping

Outer packaging:

Strong wooden boxes are usually used to provide sufficient mechanical strength.

Wooden crate suitable for large circuit breakers or international transportation

Inner packaging:

Wrap the circuit breaker with buffer materials such as foam pad, bubble film or pearl cotton to prevent vibration and collision.

For large circuit breakers, the packaging box may adopt a layered design, with accessories (such as manuals, tools, spare parts) placed on the upper layer

Our production line
Transport

Domestic transportation

If there is a designated freight forwarder in china, we willtransport the products to the designated location through road transportation or domestic express delivery after production is completed

International transport

When the quantity of goods is small and time is tight, and it needs to be transported to a designated location abroad, the three majorinternational express delivery companies are selected for transportation
DHL,FEDEX,UPS

Sea freight/air freight
When there is a large quantity of goods and time is not urgent, we choose sea freight. We will choose a suitable freight company, who wil arrange for trucks to pick up the goods and transport them to the designated por for warehousing. Finaly, they will transpored by sea to the customer's desianated port, and the customer needs to pick up the goods with a bill of lading.
