❓ Frequently Asked Questions
Q: What is the significance of the 5 A rating on the RM17TT00?
A: The 5 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: What does the 1 CO (Changeover) contact configuration on the RM17TT00 mean?
A: CO (Change Over) contacts switch between two circuits — the common terminal connects to either NO or NC depending on the device state. Used for dual-purpose indication or reversing circuits.
Q: Can the RM17TT00 relay be mounted on a DIN rail socket for easy replacement?
A: This Schneider Electric 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 RM17TT00 relay in the field without a signal source?
A: Most Schneider Electric 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.
