The MNR LNA32/100 identifies the specific variant, covering a defined shaft interface and handle travel arc. Rated for standard industrial panel integration, the mechanism provides a clear ON/OFF indication and padlockable handle position for lockout/tagout compliance. It is the part that lets an operator safely open or close the main isolator without opening the enclosure door. ## What the MNR tells you The MNR LNA32/100 is the manufacturer's ordering reference that locks the shaft interface, handle colour, and door cut-out dimensions. When replacing a handle on an existing ABB switch-disconnector, verify the installed MNR matches LNA32/100 — the shaft coupling geometry differs between variants, and a mismatched handle will not engage the switch mechanism.","metaTitle":"ABB UXAB Rotary Handle Operating Mechanism, MNR LNA32/100","metaDescription":"ABB UXAB rotary handle operating mechanism, MNR LNA32/100, current production.
