Frequently Asked Questions

What does the CR-M024DC3 catalog number indicate?
The designation breaks down as: CR-M = pluggable interface relay series, 024 = 24V coil voltage, DC = direct current coil, 3 = 3 changeover contacts.

Is the CR-M024DC3 compatible with standard relay sockets?
Yes. The CR-M series is designed as a pluggable relay, meaning it can be inserted into and removed from a matching ABB CR-M socket base without tools, simplifying maintenance and replacement.

What is the maximum switching current?
The CR-M024DC3 is rated for 10A per contact at 250V AC, suitable for direct load switching of small motors, heating elements, and control circuits.
