3PDT switching with a 24 VAC coil
The ABB CR-M024AC3 is a 3PDT relay from the CR-M series, with a 24 VAC coil — a standard control-voltage choice for panel builders working with transformer-isolated AC control circuits. Three-pole double-throw contacts give you three independent form-C contact sets per relay, which is useful for switching multiple signal paths or loads from a single coil command.
Panel fit and socket compatibility
The CR-M024AC3 mounts into the CR-M series socket family — the same footprint as the DC-coil variants — so a panel layout designed for a DC-coil version accepts this AC-coil version without a wiring change. The 24 VAC coil draws its control power from a transformer secondary; the AC coil impedance limits inrush current, which simplifies the transformer sizing compared to a DC coil with its lower cold resistance.
