  • TypeIndustrial Electrical Controls & Automation
  • ColorTransparent
  • Adjustable protection range with 9–45 A settings
  • Selectable trip class 10, 20 or 30 for motor matching
  • IEC electronic overload relay with auto and manual reset

Application fit

The Eaton XTOE045CCSS overload relay protects three-phase motor circuits in industrial control panels. It is built for maintenance teams and panel builders who need electronic overload protection with selectable trip classes. It is not suited for single-phase loads or for applications that require a built-in thermal element.

Current range

The adjustable setting spans 9 A to 45 A, covering a broad range of motor full-load currents with a single device. Trip classes 10, 20 and 30 are selectable to match different motor acceleration profiles.

Thermal behaviour

Electronic sensing eliminates the heat of traditional thermal units, so the relay runs cooler inside the enclosure. Auto and manual reset modes give flexibility after a trip event. Power draw is minimal compared with electromechanical alternatives.

Questions about this item

What does the 45 A maximum current setting mean once the relay is installed?

It is the highest overload current the relay can be set to protect; the motor will be disconnected if current exceeds the chosen setting up to 45 A.

Which trip class standards does the relay meet and what do they cap in practice?

The relay is selectable for Trip Class 10, 20 or 30, defining the maximum time it takes to trip at a given overload multiple.

What mounting style and frame size are required to fit this overload relay?

It uses a separately mounted design with Frame Size C and is compatible with Series XT Mini Contactors.
