Isolate Switch
1.Type:FN5-12
2.Standard|:IEC420 GB3804
3.Main Material:Procelain&Steel
Outline
FN5-12R(L)Model Indoor AC HV load switch - fuse Model through a comprehensive and long-term pilot test evaluation, performance to IEC420 ≤ HV load switch - fuse current ≥ (1990 version) and GB3804 ≤ 3-63KV AC High Voltage ≥ standard load switch, compared with similar foreign products, technical data has reached the international level, with small size, light weight, can be used for ring counters and box-Model substation, 10KV lines are widely used in power distribution, switching can be realized. Isolation and grounding the three-position, and effectively avoid the equipment missing running.
