Why choose it

The PXL-B10/3 combines reliable protection with compact dimensions. Its B characteristic ensures fast tripping on short circuits while avoiding nuisance trips from inrush currents typical of lighting and resistive loads. With a 10 kA breaking capacity, it handles high fault currents safely. The screw terminals accept a wide range of conductor sizes, simplifying installation. The device is designed for long service life: 10,000 electrical and 20,000 mechanical operating cycles.

Ideal use cases

• Protection of three-phase socket outlets and lighting circuits in commercial buildings
• Control circuits and small motors in industrial panels
• Distribution boards in workshops, offices, and retail spaces
• Retrofit projects where a reliable DIN-rail MCB is required

Good to know

The PXL-B10/3 is part of Eaton's xPole series, known for consistent quality and compliance with international standards. It is suitable for use in ambient temperatures up to 75 °C, though derating may apply at higher temperatures. The device has an energy limiting class of 3, reducing let-through energy and protecting downstream equipment. Always verify local regulations and coordination with upstream protective devices.
