Supplied by Ahmedabad Electric Corporation, the ABB MSAH1 is a high-rigidity shaft supporter accessory designed to stabilize extended operating shafts used with ABB Manual Motor Starters (suitable for MS116, MS132, and MO132 series). When installing door-mounted rotary handles across deep electrical enclosures or panel boards, long operating shafts require firm intermediate support to prevent sagging, alignment drift, and mechanical strain during switching operations. The MSAH1 shaft supporter holds the extended shaft firmly in alignment, ensuring smooth, precise rotary action and reducing wear on both the starter mechanism and door handle assembly
