FAQ

What does the ‘BD’ suffix in the CA3KN31BD model number signify?

The ‘BD’ suffix specifies the coil characteristics. In this case, it indicates a standard 24V DC coil. Other suffixes like ‘B7’ (24V AC) or ‘M7’ (220/230V AC) denote different coil voltages and types.

Can I add more auxiliary contacts to this TeSys K control relay?

Yes, the TeSys K series is modular. You can mount additional auxiliary contact blocks on the front of the CA3KN31BD relay, such as the LA1KN series from Schneider Electric, to expand its switching capacity.

What is the recommended screw tightening torque for the terminals on this relay?

According to the manufacturer’s specifications for TeSys K relays, the recommended tightening torque for the screw clamp terminals is 1.3 N.m (Newton-meters). Proper torque is crucial to ensure a secure connection and prevent overheating.
