Operating temperature range spans -40 °C to 75 °C, with a derating curve applied above 30 °C: at 40 °C the continuous rating drops to 15.2 A, at 50 °C to 14.4 A, and at 70 °C to 12.32 A — a critical consideration for sealed enclosures or high-ambient locations like a pump house or rooftop panel. Mounting position is unrestricted — the RCBO can be installed horizontally or vertically without derating the thermal-magnetic trip curve, simplifying panel layout. Supply can enter from either top or bottom, and the device is halogen-free and silicon-free — important for environments sensitive to outgassing, such as clean rooms or aerospace assembly. ## Where it goes — deployment context IP20 rated with conductors connected and the board closed — it is not a standalone outdoor device; it belongs inside a weatherproof enclosure if installed in a damp or dusty environment.","metaTitle":"Siemens 5SU1653-7KK16 SENTRON RCBO, 1P+N, 16 A, C-curve, 4.5","metaDescription":"Siemens 5SU1653-7KK16 SENTRON RCBO, 1P+N, 16 A, C-curve, 4.5 kA per EN 60898, 15 kA per IEC 60947-2. 2 MW wide, halogen-free, silicon-free.
