It mounts to the breaker front cover and lets you trip or reset the breaker from a control panel door or a remote station via a flexible cable, keeping the arc flash boundary outside the operator's reach during normal switching. This is not a standalone breaker — it is the mechanical interface that converts rotary handle motion through a cable pull, sized for the 3VA5 and 3VA6 frames at 400 A and 600 A respectively. The Bowden wire actuator version means the operator station can be located several feet from the breaker — useful when the breaker is deep inside a panel or in a restricted-access enclosure where a direct rotary handle would be impractical. Compatibility is limited to the 3VA5 and 3VA6 frame sizes at 400 A and 600 A; it will not fit the smaller 3VA1/2 frames or legacy 3VL breakers without an adapter plate that Siemens does not list for this order code.","metaTitle":"Siemens 3VA9448-0CB10 SENTRON Max-Flex Bowden Wire Actuator","metaDescription":"Siemens SENTRON 3VA9448-0CB10 Max-Flex switch module with Bowden wire actuator for 3VA5/6 400/600 breakers.
