The Siemens 5SU1354-3KK06 is a SENTRON RCBO combining overcurrent protection (characteristic B, 6 A rated) with residual current detection (Type F, 30 mA trip threshold) in a single 2-module-wide (36 mm) package for 1P+N circuits. Type F residual current detection handles sinusoidal AC faults, pulsating DC faults, and composite faults up to 1 kHz — the standard for single-phase inverter-fed loads like washing machines, heat pumps, and LED drivers where Type A may nuisance-trip on high-frequency leakage.
Temperature derating — the real continuous current ceiling
The mounting position is unrestricted, but the derating curve assumes free convection — stacking in a sealed enclosure without ventilation shifts the effective ambient upward.
Panel fit — 2 MW, 36 mm, any position
IP20 with the distribution board installed and conductors connected — the RCBO itself is not sealed against washdown; it lives inside a cabinet.
Lifecycle and sourcing — active production, quoted to order
No stock-holding claim — each order is quoted to the buyer's required volume.
