Siemens SENTRON 5SU1346-7FP13 — 4-pole RCBO, 13 A C-curve, 30 mA Type A
The 4 MW (72 mm) width and IP20 finger-safe terminals mean it snaps into a standard 4-module DIN-rail slot in a consumer unit or panelboard.
At 13 A rated current, the RCBO handles continuous loads up to that value; derate per the temperature table: 12.2 A at 40 °C, 11.7 A at 45 °C, 11.2 A at 50 °C, 10.8 A at 55 °C, and 10.3 A at 60 °C ambient. Type A residual current detection covers pulsating DC fault currents from rectified loads (SMPS, LED drivers, VFDs) in addition to sinusoidal AC — important for modern panels with electronic loads. The 4 kV rated surge voltage withstand confirms coordination with standard SPDs at the service entrance.
Supply can enter from either top or bottom, and mounting position is unrestricted — install it in any orientation within the distribution board. The IP20 protection rating applies when the board is installed with conductors connected; the enclosure itself provides the additional ingress protection for the panel environment. Depth is 72 mm, installation depth 70 mm, height 85 mm — fits standard 4-module cutouts in consumer units and panelboards.
