The ABB CR-M024AC4L is a 4PDT relay with a 24 VAC coil, part of the CR-M series of industrial control relays. It sits in the Relays & Sockets subcategory, used for switching loads in control panels, motor starters, and general automation circuits where four independent contact sets are needed.
The 4PDT contact arrangement gives you four form-C (changeover) contact sets in a single relay package, saving DIN-rail space compared to stacking multiple 2-pole relays. The CR-M series uses a standard octal-style base; verify socket compatibility if replacing an existing relay in a panel.
