EATON PXF-63/4/003-A Residual Current Circuit Breaker (RCCB), 63 A, 4-Pole, 30 mA, Type A

For installations where pulsating DC residual currents may occur, the EATON PXF-63/4/003-A offers dependable protection that goes beyond basic AC-only devices. This 4-pole RCCB is engineered to detect both sinusoidal AC and pulsating DC earth leakage currents, making it a robust choice for modern electrical systems with electronic loads.

Highlights

• Rated residual operating current of 30 mA for personal protection against electric shock
• Type A tripping characteristic: sensitive to AC and pulsating DC residual currents
• High 63 A rated current and 10 kA conditional short-circuit withstand capacity
• Compact 4-module DIN rail design for easy installation in distribution boards
• Complies with IEC/EN 61008, ensuring safety and performance consistency

In daily use

Installation is straightforward on a standard 35 mm DIN rail, with clearly marked terminals accepting solid or stranded conductors from 1.5 to 35 mm². The device operates reliably across a wide temperature range from -25 °C to +40 °C, and its IP20 terminal protection suits indoor electrical enclosures. A mechanical lifespan of 20,000 operations and electrical endurance of 10,000 cycles mean it will serve for years without degradation.
