It ships as a complete assembly with door interlocking, a 24 V DC illumination kit, and a door-open position accessory. ## Sealing and deployment Rated IP65 and NEMA 4, 4X. The operator face withstands hose-down cleaning and outdoor weather. The door interlocking feature prevents opening the enclosure door while the breaker is in the ON position, which is a typical safety requirement for motor control centers and machine disconnect panels. ## Panel fit The mechanism measures 138 mm wide by 94 mm high. That footprint matches the standard door cutout for 3VA5/6 breakers in the 400/600 A frame range. Verify the door thickness and handle projection against your enclosure — the interlock and illumination kit add depth behind the door.","metaTitle":"Siemens 3VA9447-0FK47 SENTRON Door-Coupling Rotary Operator,","metaDescription":"Siemens 3VA9447-0FK47 SENTRON door-coupling rotary operating mechanism for emergency-off.
