12kV Indoor load breaker switch FKRN12
The FKRN12 indoor load breaker switch is an indoor high-voltage power distribution device adapted to 12kV, 50Hz three-phase AC power systems. The device features a highly integrated overall structure, combining the load switch body, spring operating mechanism, grounding switch, fuse installation components, and five-proof interlocking system into one compact and reasonable layout, significantly saving internal installation space in the switchgear. It is compatible with various standard HXGN ring main units and non-standard complete sets of power distribution equipment, offering convenient installation and strong adaptability. This load switch has a rated voltage of 12kV, and rated currents covering mainstream specifications such as 125A, 200A, 400A, and 630A. The rated short-time withstand current can reach 20kA.A variety of current and voltage schemes are available.
