The Siemens 5SU1354-4KK13 is a SENTRON RCBO combining a 13 A MCB with a Type F RCD in a 2-module-wide (36 mm) housing. Type F detects sinusoidal AC, pulsating DC, and mixed-frequency residual currents up to 1 kHz.
Ratings that matter for the panel
Power loss maxes at 4.4 W full-load, which keeps heat manageable in a packed enclosure. Ambient operating range is -25 to +55 °C, with a derating curve starting at 30 °C (13 A nominal) down to 10.01 A at 70 °C — useful when the RCBO sits near heat sources inside the panel.
Mounts on standard DIN rail, any position.
