Eaton XTOE045DCS Electronic Overload Relay

This Eaton XTOE045DCS electronic overload relay protects three-phase motors by monitoring current between 9 A and 45 A. It suits maintenance engineers and panel builders who need adjustable trip classes of 10, 20 or 30 for IEC-style motor starters. The unit fits directly onto compatible XT mini contactors with frame size D.

Direct contactor mounting with 1NO/1NC auxiliary

The relay mounts directly to the contactor, reducing panel wiring and saving DIN-rail space. A built-in 1NO/1NC auxiliary contact provides immediate status feedback for control circuits. Transparent housing allows visual inspection of the setting dial and trip indicator during routine checks.

Adjustable 9 A to 45 A range

The single specification that decides fit is the 9 A to 45 A adjustment range combined with selectable Class 10, 20 or 30 trip curves. If the motor full-load current falls outside this window or the application demands a fixed trip class not listed, this relay will not meet the requirement.

Questions about this item

What trip classes does the XTOE045DCS electronic overload relay support, and what does that limit?

The relay operates at Class 10, 20 or 30, which sets the maximum time allowed for the device to trip under overload conditions.

What mounting style and frame size are required to fit the XTOE045DCS relay?

It mounts directly to a contactor using Frame Size D and is compatible with Series XT mini contactors.

How is the XTOE045DCS relay installed, and which step is commonly missed?

Mount the relay directly onto the compatible Series XT mini contactor, then set the current dial between 9 A and 45 A; the step often missed is selecting the correct trip class (10, 20 or 30) for the application.
