Product details

The Siemens 5SU9356-7KK16 is a SENTRON RCBO — an RCD-operated circuit breaker combining overcurrent and residual-current protection in a single 2-module-wide (36 mm) package. 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).

Frequently asked questions

What is the breaking capacity of 5SU9356-7KK16?

6 kA per EN 60898 and 10 kA per IEC 60947-2. The IEC figure applies when the device is used as a circuit breaker under that standard, giving higher fault-current capability.

What does the C-curve mean on this RCBO?

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.

Will 5SU9356-7KK16 drop into a panel specified around 5SL6550-7BB?

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.

What compliance documentation does Siemens provide for 5SU9356-7KK16?

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.

Where can I buy 5SU9356-7KK16?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an inquiry for a firm commercial offer.
