FAQ

Question?

What is the coil voltage for this CA3DN22MD relay?

Answer

The ‘MD’ suffix in the model number designates a 220V AC coil, compatible with 50/60Hz power systems.

Question?

Can I use this relay to directly switch a motor?

Answer

No, this is a control relay (auxiliary contactor) with a 10A thermal current rating (Ith). It is designed for switching control circuits, not for high-power motor loads. For motor switching, you would need a power contactor.

Question?

Is the Schneider Electric CAD32MD a direct drop-in replacement?

Answer

The CAD32MD is the recommended modern replacement, but it features a different contact configuration (3 NO + 2 NC) compared to this model’s 2 NO + 2 NC. Wiring modifications may be necessary depending on your specific application.
