Allen-Bradley 198-MR1 External Reset Button

Allen-Bradley 198-MR1 External Reset Button is a gray, flush-mount pushbutton that provides an external reset control for select overload-relay configurations in Allen-Bradley panels. This external reset kit is designed for molded plastic enclosures and is sold as 100-A KIT 198-MR1, part of Rockwell’s 198-MR family of panel accessories. The 198-MR1 button is labeled R/RESET and is intended for use with bimetallic overload relays and SMP overload relays, including SMP-1 and SMP-2, per Rockwell documentation. When installed in a compatible enclosure, it offers a clearly accessible reset mechanism without opening the enclosure, supporting safe, manual reset of the protection circuit after a trip. As with other 198-series reset accessories, it is an enclosure-mounted component intended to complement the broader set of overload-relay protection options within industrial control panels.
