Eaton PXK-B16/1N/003-F Interruptor combinado RCBO, B16 1P+N 30mA Tipo A, 230V, 6kA, 2TE

This Eaton RCBO merges residual current protection and overcurrent protection into a single 2-module device, eliminating the need for separate RCD and MCB units in final circuits. The PXK-B16/1N/003-F is rated at 16 A with B-curve tripping and a 30 mA Type A residual current sensitivity, making it particularly suited for circuits with electronic loads that can produce pulsating DC fault currents. Its 6 kA breaking capacity and energy limiting class 3 provide robust short-circuit performance in residential and commercial distribution boards.

Highlights

• Combined RCBO: residual current (30 mA, Type A) and overcurrent (B16, 1P+N) in one unit
• Compact 2 TE (35 mm) DIN rail mounting saves space in consumer units
• Rated voltage 230 V AC, 50/60 Hz, with 6 kA short-circuit breaking capacity
• Screw terminals accept 1–25 mm² solid or 1–16 mm² flexible conductors
• IP20 terminal protection (IP40 when installed in an enclosure)
• Complies with EN 61009-1 and VDE 0664-20

In daily use

Installation is straightforward: the device clips onto a standard 35 mm DIN rail and occupies only two modules. The screw terminals provide a secure connection for a wide range of conductor sizes, and the clear labeling on the front face simplifies circuit identification. The B-curve characteristic ensures fast tripping on short circuits while avoiding nuisance trips from inrush currents typical of lighting and socket circuits. The Type A residual current detection handles both sinusoidal AC and pulsating DC fault currents, making it suitable for modern installations with electronic appliances.
