IEC Control Relay for Industrial Automation

The Eaton XTRE10B40C is an IEC control relay designed for industrial electrical automation. It provides four normally open contacts rated at 10 A for 24 V DC switching and 6 A at 240 V AC. The coil operates on 415/480 V AC at 50/60 Hz, drawing 3.3 VA. It mounts on a standard DIN rail and uses screw terminals for secure wiring connections.

Sustained Load Behaviour and Contact Ratings

Under continuous operation the relay maintains its 10 A DC and 6 A AC contact ratings within the specified 140 °F maximum operating temperature. The IEC frame size of 45 mm and IP20 enclosure protect the contacts in typical cabinet environments. Power consumption remains steady at 3.3 VA, and the unit is compatible with the Series XTRE control relay line for consistent performance across matched components.

Thermal Performance and Power Draw in Normal Use

In normal use the relay dissipates heat through its transparent housing measuring 1.77 in wide, 2.68 in high and 2.95 in deep. The IP20 rating limits ingress without active cooling, so airflow within the enclosure manages temperature rise. Coil power stays at 3.3 VA during energised periods, and the screw-terminal connections remain stable across the 50/60 Hz supply range.

Questions about this item

How much heat does the 3.3 VA coil generate during continuous operation?

The coil consumes 3.3 VA at 415/480 V AC; heat output scales with that power draw inside the IP20 enclosure.

What mounting hardware and supply voltage are required to install the relay?

It mounts on a DIN rail using screw terminals and requires a 415/480 V AC coil supply at 50/60 Hz.

Can the 10 A / 240 V AC contacts switch loads on a legacy 240 V control panel?

Yes, the 4NO contacts are rated 6 A at 240 V AC and 10 A at 24 V DC for compatible legacy circuits.
