Eaton PXK-C16/1N/003-A RCBO, 16 A, 30 mA, Type A, C-Curve, 1P+N

The Eaton PXK-C16/1N/003-A stands out as a combined residual current circuit breaker with overcurrent protection (RCBO) that integrates a 16 A miniature circuit breaker and a 30 mA residual current device into a single 1P+N module. Unlike separate MCB and RCD setups, this unit saves space on the DIN rail while providing complete protection against overload, short-circuit, and earth fault currents. Its Type A residual current detection ensures reliable tripping for both alternating and pulsating direct fault currents, making it suitable for circuits with electronic loads. The C-curve characteristic handles moderate inrush currents, ideal for lighting, socket outlets, and mixed residential or commercial final circuits.

Highlights

• Rated current 16 A with C-curve tripping characteristic
• 30 mA residual current sensitivity for personal protection
• Type A residual current detection (AC and pulsating DC sensitive)
• Rated voltage 230 V AC, 50/60 Hz
• Rated switching capacity 6 kA
• 1P+N configuration – protected phase with switched neutral
• Compact DIN-rail mounting for space-saving installation
• Terminals suitable for 1-25 mm² solid and 1-16 mm² stranded conductors

In daily use

This RCBO is designed to be installed in standard distribution boards on a 35 mm DIN rail. The C-curve characteristic allows moderate inrush currents, making it a versatile choice for general-purpose final circuits. The Type A residual current function provides enhanced protection in environments where electronic equipment may generate DC fault currents. Its wide operating temperature range from -25 to +50 °C ensures reliable performance in various installation conditions. The device features a clear status indication and a test button for regular functional checks.
