A Type Manual Operation Mechanism | Actuator for 12kV/24kV Indoor SF6 Load Break Switch (LBS)

The A type manual operation mechanism is a high-reliability actuator designed for FLRN36-12D/T100-31.5 and FLN36-12D/630-20 indoor high voltage SF6 load break switches. Suitable for 12kV and 24kV switch corollary equipment, this mechanism operates based on a compression spring release principle. It provides three essential working positions: closing, opening (break-brake), and grounding. Featuring a moderate size for convenient installation and wide applicability, the A type mechanism is equipped with a shunt tripping coil and supports fuse-fusing break-brake functions. This agency is fully compliant with the technical requirements of GB3804-1990 (for 3-63kV AC high voltage load switches) and GB16926-1997 (for electric AC high voltage load switch and fuse combinations).
