❓ Frequently Asked Questions

Q: What is the significance of the 38 A rating on the 3RW40281BB14?

A: The 38 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 3RW40281BB14 has a coil voltage of 110–230V AC/DC — what control supply is needed?

A: This Siemens device requires a 110–230V AC/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.
