❓ Frequently Asked Questions

Q: What is the significance of the 4.5–18 A rating on the LUCA18BL?

A: The 4.5–18 A rating is the device’s maximum continuous current carrying capacity under specified conditions (typically 40°C ambient). For circuit design, use 80% of this value as the design current to allow for derating due to grouping, temperature, and future load growth.

Q: The LUCA18BL has a coil voltage of 24V DC — what control supply is needed?

A: This Schneider Electric device requires a 24V DC control supply connected to the coil terminals (A1 and A2). For DC coils, observe polarity where marked. DC coils produce no inrush and are preferred for PLC output cards. Always fit a surge suppressor across the coil when switching with a PLC or solid-state relay.
