Product Description

General
The series of VPN-12 Vacuum Circuit Breaker use domestic seal electrode mast structure which is indoor power distribution equipment of 3phases AC 50-60HZ and rated voltage 12KV.
It acts as protection and control element for electric network equipment and mine companies' power equipment. It partly adopts APG technique which protect vacuum arc extinguish chute. It prevents the major circuit components from damage of collision, dust as well as dew. It is applicable to frequent operations of rated electricity, multiple short circuit current switch, as well as severe environment.

Test
VNP-12 has passed type test according to national standards. The machine can reach to 20000 times by level M2 and short circuit current breaking can reach to 274 times by level E2. All the products have passed through quality inspection before delivery, which ensures safety run under normal environment.

Shipment Inspection: Mechanical feature test, major circuit frequency withstand voltage test, control circuit insulated test, major circuit resistance test, interlocking operation test, Mechanical and electric operation test.

Features
1. Long mechanism and electricity service life
2. No maintenance effort
3. Intelligent vacuum circuit breaker with full voice dialogue, data backup, communication and other functions
4. High credibility with vacuum arc extinguish chute of high quality
5. Reduce installation and adjustment, improve mechanical credibility
6. Enhance the distance of major circuit to improve resistance ability of dirt coordinate inductance and electric capacity load reasonably
7. High feasibility, can be exchange with other domestic products of the same type.

It has passed complete test, part test result Q(pc) less than 1 pc(1.2UM/√ 3=8.3KV voltage)

Application Field

VNP-12 vacuum circuit breaker can be used in various and diverse industries, such as electric power, metallurgy, petroleum, chemistry and urban construction etc.
VNP-12 vacuum circuit breaker can be used in 12kv power distribution system, and is applicable for controlling and protecting cables, overhead wires, transformers, motors, generators and capacitors.

Operating Environment
VNP-12 vacuum circuit breaker is applicable to the normal operating environment as well as special operating environment with dramatic temperature change, climate change or other special conditions. If the product is used above the altitude of 1000, or under the temperature exceeding 20 Celsius degree, please do communicate with the manufacture on relevant manufacturing technology.
