The 5SU1154-6KK13: Compared to a standard MCB-only device like the 5SL4363-7, this RCBO integrates the residual-current function, so it occupies the same two-module footprint but eliminates the need for a separate RCCB upstream — saving a DIN position and reducing wiring. The 10 mA trip level is lower than the common 30 mA, making it suitable for circuits where enhanced personnel protection or equipment sensitivity is specified.
Depth is 77 mm, installation depth 70 mm — verify enclosure depth clearance, especially in shallow consumer units. IP20 applies when installed in a closed distribution board with connected conductors.
Derating is required at elevated ambient temperatures: at 30 °C the rating is 13 A, dropping to 12.48 A at 40 °C, 11.96 A at 50 °C, and 10.01 A at 70 °C. Halogen-free and silicon-free construction suits environments sensitive to corrosive off-gassing, such as marine or offshore installations. The residual current type A detects AC and pulsating DC faults, covering most modern electronic loads.
