The design is instantaneous (no intentional time delay on the residual-current side). The supply voltage frequency is 50 Hz; operating frequency range is 50/60 Hz. Supply can land on either top or bottom terminals. ## Breaking capacity — the number that decides coordination Rated short-circuit breaking capacity is 10 kA according to EN 60898 and 20 kA according to IEC 60947-2. That dual rating matters for panel coordination: EN 60898 governs residential and light commercial final circuits, while IEC 60947-2 applies in industrial distribution where higher prospective fault currents are common. The 20 kA figure gives headroom for industrial panelboards without needing an upstream current-limiting MCCB. ## Thermal derating — don't spec the 30 °C number blindly The 16 A rating derates with ambient temperature inside the enclosure. At 40 °C it carries 15.2 A; at 50 °C it drops to 14.4 A; at 60 °C it's 13.6 A; at 70 °C it's 12.32 A. Current production — no end-of-life notice.","metaTitle":"Siemens SENTRON 5SU1324-7KX16 RCBO, 2P 16A C-curve, 10kA/20k","metaDescription":"Siemens 5SU1324-7KX16 SENTRON RCBO, 2-pole, 16 A rated at 30 °C, C-curve, 10 kA per EN 60898 / 20 kA per IEC 60947-2.
