Eaton PXF-25/4/003-A prúdový chránič (RCCB), 25 A, 4-pólový, 30 mA, typ A

Electrical faults can occur without warning, endangering both people and equipment. The Eaton PXF-25/4/003-A residual current circuit breaker detects dangerous leakage currents and disconnects the circuit within milliseconds, preventing electric shocks and reducing fire risks. This 4-pole RCCB is rated for 25 A and offers a residual current sensitivity of 30 mA, making it suitable for protecting circuits in residential, commercial, and light industrial installations.

Who is it for

Electricians, panel builders, and facility managers who need reliable residual current protection for three-phase systems. It is ideal for distribution boards supplying power to sockets, lighting, and equipment where personal safety is paramount.

Main features

• Type A residual current protection: detects alternating and pulsating direct residual currents.
• 4-pole design for three-phase networks with neutral.
• Rated current 25 A, suitable for common branch circuits.
• 30 mA trip sensitivity for personal protection.
• DIN rail mounting for quick installation in standard distribution boards.
• Complies with IEC/EN 61008, ensuring safety and performance.

Tips

Always test the RCCB using the test button after installation and periodically thereafter to ensure proper operation. For circuits with electronic loads that may produce smooth DC residual currents, consider a Type B RCCB. Ensure the upstream overcurrent protection is coordinated with the RCCB's rated short-circuit capacity.
