Product Description

General
The main design concept of VPN-24 Vacuum Circuit Breaker includes: The main circuit using solid seal pole, and improving the design of operating mechanism, so that the reliability, mechanical capability and circuit performance of the circuit breaker insulation can be greatly improved. Thus can truly achieve the aim of free maintenance and longer mechanical and electric life; Developing the serialization of products to meet different demands of using.

Test
VPN-24 Vacuum Circuit Breaker has passed all kinds of type-testing according to the national standards including: 10000times mechanical life test by level M2, and 20 times electric life test by breaking short-circuit current by level E2. Thus ensures safe operation under normal conditions of use.
Shipment Inspection: Mechanical characteristics test, power-frequency withstand voltage test of the primary loop, interlocked operation test, mechanical and electric test.

Features
1. No need to reignite through the movable capacitor banks test;
2. High universality: It can be completely exchanged by VD4 and VEP switch as well as adapted to ASN2, AMS and ZS1
3. Perfect series design. The operating mechanism can either be spring or permanent magnetic, and the structure can either be front or side mounted.
4. The product has passed national appraisal and the type testing by GBI1984-2003 standard. It also reaches the level M2-E2-C2 of the breaker.

Environment Requirement
No serious pollution from dust, fume, corrosive and/or combustible gas, steam or salt mist.
Earthquake intensity should be no more than8.0-magnitude horizontal acceleration: Synthetic seismic wave 0.25g, Sinusoidal resonant beat-wave0.15g
The amplitude of the electromagnetic interference in the secondary system should be no more than1.6kv
Customers can contact with our company to discuss the scope an d technical measures if the environment is outside the range of above.
