It carries NEMA ratings 1, 3R, and 12, meaning the assembly is suitable for indoor enclosures (NEMA 1), outdoor weatherproof installations (NEMA 3R), and general-purpose industrial locations where dust and dripping non-corrosive liquids are present (NEMA 12). This Max-Flex kit is specified for 3VA5 and 3VA6 molded-case circuit breakers in the 400 A and 600 A frame sizes. The Bowden wire actuator allows the breaker to be tripped or switched from a remote location — useful when the breaker is mounted deep inside a panel or in a restricted-access enclosure. The NEMA 12 rating means the actuator handle assembly can be installed in a dust-tight, drip-proof industrial panel without additional sealing.","metaTitle":"Siemens 3VA9448-0CK12 SENTRON Max-Flex Kit, Bowden Wire Actu","metaDescription":"Siemens 3VA9448-0CK12 SENTRON Max-Flex kit with Bowden wire actuator for 3VA5/6 400/600 breakers.
