EATON PXF-40/2/003-A interruttore differenziale (RCCB), 2 poli, 40 A, 30 mA, tipo A, 230/400 V AC

The EATON PXF-40/2/003-A stands out among residual current devices by combining a compact 2-module footprint with a robust 40 A rating and sensitive 30 mA tripping, making it a dependable choice for protecting circuits against earth leakage currents in residential and commercial installations. Its Type A classification ensures reliable detection of both sinusoidal AC and pulsating DC residual currents, a critical advantage in modern electrical systems with electronic loads.

Highlights

• Rated residual current of 30 mA for personal and fire protection
• Type A tripping suitable for AC and pulsating DC fault currents
• 40 A rated current supports high-load circuits
• Compact 2-module width saves space on DIN rail
• Complies with IEC/EN 61008 for proven safety

In daily use

Installed on a standard 35 mm DIN rail, this RCCB provides continuous monitoring of circuit integrity. Its instantaneous tripping characteristic ensures rapid disconnection in the event of a fault, minimizing the risk of electric shock or fire. The device operates reliably across a wide temperature range from -25 to +40 °C, and its IP20 terminal protection (IP40 when enclosed) suits typical distribution board environments. Terminals accept solid or stranded conductors from 1.5 to 35 mm², simplifying wiring for a variety of cable sizes.
