The Siemens SENTRON 3VA9477-0FH45 is a red/yellow pistol-grip lever handle for door-mounted rotary operators, designed as an accessory for 3VA51/52/53/54 frames (125 A to 600 A) and 3VA61/62/63/64 frames (150 A to 600 A). The NEMA 4X rating means the handle assembly withstands washdown and corrosive environments — suitable for food-processing or chemical plant enclosures where the operator must be mounted through the door.
Panel Integration
The handle mounts through the enclosure door and interfaces with the rotary operator shaft of the SENTRON 3VA molded-case switch. NEMA 4X sealing is maintained at the door cutout when installed per the manufacturer's torque and gasket instructions.
