FAQ

What is the coil voltage and type for this CA2-EN 322B relay?

The ‘B’ suffix in the model number CA2-EN 322B specifically indicates a 24 Volt DC (Direct Current) coil.

Can this Telemecanique relay be used as a direct replacement for a modern Schneider Electric CAD series relay?

No, not directly. While the Schneider CAD series is the modern functional replacement, the dimensions, wiring layout, and exact contact configurations may differ. The CA2-EN 322B is primarily for replacing an identical unit in an existing system. Retrofitting would require careful review of the technical datasheets.

What are the A600 and Q600 ratings specified on the label?

These are NEMA (National Electrical Manufacturers Association) and UL (Underwriters Laboratories) contact ratings. ‘A600’ refers to AC resistive loads, while ‘Q600’ refers to AC inductive loads (like motor control circuits), both with a maximum voltage of 600V. They define the current-making and breaking capabilities of the contacts under specific AC voltage conditions.
