Application Scope

The Eaton XTOMP24AC1 is a thermal overload relay designed for three-phase motor protection in industrial control panels. It suits maintenance engineers and panel builders who need IEC-style overload protection for small motors drawing between 0.16 A and 0.24 A. The unit mounts directly onto compatible Series XT mini contactors, simplifying assembly in space-constrained enclosures. Buyers requiring higher current ranges or NEMA-sized starters must select a different relay frame.

Current Range and Trip Behaviour

The adjustable setting spans a minimum of 0.16 A and a maximum of 0.24 A, providing a narrow window for precise protection of fractional-horsepower loads. Trip Class 10 ensures the relay opens within ten seconds at six times the set current, limiting thermal stress during locked-rotor conditions. Auto and manual reset modes give operators flexibility after a trip event. Motors with full-load currents outside the 0.16 A to 0.24 A band cannot be protected by this device.

Integration Requirements

Direct mounting onto Series XT mini contactors eliminates the need for separate DIN-rail space and additional wiring between contactor and relay. The built-in 1NO/1NC auxiliary contact block supports both signalling and control-circuit interlocking without extra accessories. Frame Size A dimensions match the contactor footprint, keeping the starter assembly compact. Panels using non-XT contactors or larger frame sizes will require a different mounting strategy.

Questions about this item

Will the XTOMP24AC1 fit my existing XT Mini Contactor frame size A?

Yes, it mounts directly to Series XT Mini Contactors with frame size A.

How can I confirm the relay is operating correctly after installation?

The Trip Class 10 thermal protection and auto or manual reset will activate within the 0.16 to 0.24 A current range.

Does the package include mounting hardware or must I order it separately?

Mounting hardware is not included; the relay attaches directly to the contactor without extra parts.
