It is an accessory, not a standalone breaker, sized for the 3VA6 150/250 and 3VA5 250 molded-case frames. Rated IP65 and NEMA 4/4X, so the operator itself seals against hose-directed water and dust ingress when the door is closed — suitable for washdown environments and outdoor enclosures where the panel interior must stay dry. The 105 mm width and 82 mm height define the cutout and bezel footprint on the enclosure door; verify the panel door prep matches these dimensions before cutting. ## Door interlock and open-position feature The mechanism includes a door interlock and a door-open position accessory — meaning the door cannot be opened with the breaker in the ON position unless the operator is in the OFF or TRIPPED state, and the handle also allows the door to be opened when the breaker is OFF for maintenance access.","metaTitle":"Siemens 3VA9277-0FK41 SENTRON Door-Coupling Rotary Operator,","metaDescription":"Siemens 3VA9277-0FK41 SENTRON door-coupling rotary operating mechanism.
