It is also not intended for outdoor use without a suitable weather-resistant enclosure.

Key specifications

• Number of poles: 3
• Rated current: 25 A
• Rated voltage: 400 V
• Tripping characteristic: B
• Breaking capacity: 10000 A
• Protection rating: IP20

The Eaton PXL-B25/3 is designed for standard DIN-rail mounting within an electrical distribution cabinet. Installation should be performed by a qualified electrician to ensure all connections are secure and compliant with local electrical regulations. The device snaps easily onto the rail, and the terminals are designed to accommodate standard wiring sizes used in typical distribution systems.

What to consider before purchase

• Verify that the 25 A rating matches your circuit requirements
• Ensure the 3-pole configuration is compatible with your power supply
• Check that the B-characteristic is suitable for your specific load type
• Confirm the available space in your distribution board

For optimal safety and longevity, ensure that all electrical connections are tightened to the manufacturer's specified torque settings and perform periodic inspections of the distribution board to ensure no signs of thermal stress or loose wiring are present.
