1SAM201920R1000

ABB 1SAM201920R1000 MSH-AR is a shaft alignment ring designed for door-coupling applications of ABB manual motor starters and motor protection circuit breakers. It is used with MSHD/MSH rotary handles and OXS6 operating shafts to maintain correct shaft alignment between the motor starter installed inside an electrical enclosure and the external operating handle mounted on the panel door. The accessory is suitable for ABB MS116, MS132 and MS165 ranges and is particularly important when longer extension shafts are used.
