MSH-AR – ABB | MSH AR SHAFT ALIGNMENT RING

Description

The ABB MSH-AR Shaft Alignment Ring (1SAM201920R1000) is an essential door coupling accessory engineered to support and guide extension shafts for manual motor starters. Designed for seamless compatibility with MSHD and MSH handles, the MSH-AR assists in aligning long OXS6 shafts to the handle inlet when operating ABB MS116, MS132, or MS165 manual motor starters mounted at the rear of a switch cabinet.

This alignment ring is mandatory for the proper installation and stabilization of shafts longer than 105 mm (up to a maximum shaft length of 180 mm). By ensuring precise mechanical alignment and smooth rotational operation from outside the enclosure, the MSH-AR guarantees reliable external control panel actuation.
