Allen-Bradley 800MR-A5AK Relay

The Allen-Bradley 800MR-A5AK is a 22 mm flush-mount pushbutton operator in white, designed for panel installations in industrial control applications. It is part of the 800MR family and the A5AK variant provides four contact circuits: one normally open (NOC) and three normally closed (NCC) contacts, with large-screw terminals to simplify field wiring. The operator’s flush head and 22 mm footprint enable tidy, low-profile control stations, and it is designed to be paired with compatible 22 mm contact blocks and mounting hardware to tailor the circuit for start/stop, signaling, or selector functions in control panels. By using Allen-Bradley 22 mm pushbutton accessories, this model achieves consistent fit and wiring across machines, facilitating replacement and modernization of panels without changing the surrounding footprint.
