❓ Frequently Asked Questions

Q: What is the significance of the 10 A rating on the TC303CX?

A: The 10 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: Can the TC303CX relay be mounted on a DIN rail socket for easy replacement?

A: This Selec relay typically requires direct panel or DIN rail wiring. For applications requiring frequent relay replacement, consider the plug-in relay variant of this series with a matching socket base.

Q: How do I test the TC303CX relay in the field without a signal source?

A: Most Selec relays can be manually forced using the test button (if fitted) — this mechanically closes the relay contacts without energising the coil, allowing functional testing of the controlled circuit. For coil testing, use a multimeter to measure coil resistance (typically 500–2000Ω for AC coils at rated voltage) and compare with datasheet values.
