Supplied by Ahmedabad Electric Corporation, the ABB MSMN is a precision shaft driver adapter complete with a securing screw, specifically engineered to connect operating shafts to ABB Manual Motor Starters (MS116, MS132, and MS165 series). Designed with a standard $6 times 6 text{ mm}$ square shaft receptacle, this driver component couples directly onto the rotary switch mechanism of the motor starter. It enables reliable engagement with extension shafts and door-mounted operating handles (such as MSHD series handles) for seamless external rotary switching. Constructed from high-durability, impact-resistant industrial thermoplastic and equipped with a heavy-duty mounting screw, the MSMN driver ensures firm locking, minimal mechanical backlash, and accurate rotary control over long operational lifetimes.
