It's a 1P+N design, meaning it switches and protects the phase conductor only, with the neutral switched but not protected. ## Temperature derating and panel placement At 40 °C it derates to 15.04 A, at 45 °C to 14.56 A, at 50 °C to 13.92 A, and at 55 °C to 12.96 A. If your distribution board runs warm — typical in a crowded DIN-rail enclosure — size the load accordingly. The device is rated for any mounting position and accepts supply from either top or bottom, which simplifies panel wiring. Installation depth is 70 mm; total depth including terminals is 77 mm. Width is 36 mm (2 modular units).","metaTitle":"Siemens 5SU9356-7KK16 SENTRON RCBO, 16A C-curve, 6kA, 1P+N","metaDescription":"Siemens 5SU9356-7KK16 SENTRON RCBO, 16A rated at 30°C, C-curve, 6kA (EN 60898) / 10kA (IEC 60947-2), 1P+N, 2 MW.

The IEC figure applies when the device is used as a circuit breaker under that standard, giving higher fault-current capability."},{"question":"What does the C-curve mean on this RCBO?","answer":"Magnetic trip threshold is 5 to 10 times the rated current (In). For the 16 A version, that's 80–160 A instantaneous trip — suitable for circuits with moderate inrush like small motors, transformers, or capacitor banks."},{"question":"Will 5SU9356-7KK16 drop into a panel specified around 5SL6550-7BB?","answer":"Both are 2-MW (36 mm wide) RCBOs from the SENTRON family, so the physical footprint matches. But 5SL6550-7BB is a different rating and characteristic — verify the load current, breaking capacity, and curve before substituting. The 5SU9356-7KK16 is a 16 A C-curve; the 5SL6550-7BB may differ."},{"question":"What compliance documentation does Siemens provide for 5SU9356-7KK16?","answer":"The device is halogen-free and silicon-free. It carries ratings per EN 60898 and IEC 60947-2, overvoltage category III, pollution degree 2. Standard Siemens declarations of conformity cover CE, UKCA, and RoHS — request the specific document bundle with your RFQ."},{"question":"Where can I buy 5SU9356-7KK16?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
