Product Details

Company product introduction

FKN12A-12D pressure type load switch, FKRN12A-12D series pressure type load switch-fuse combination device, suitable for 12KV and below three-phase distribution system, as the control and protection of power equipment such as transformers, cables, overhead lines, etc. It is especially suitable for terminal substations and box substations in urban networks and rural power grids. And applies to ring network, dual radiation power supply unit control and protection.

FKN12A-12D Series Compressed Load Switch can Split Load Current and Overload.

FKN12A-12D Series Compressed Air Load Switch - Fuse combination can be divided into load current, overload current, breaking line short-circuit current
