The Siemens 5SV9313-7NK10 is a SENTRON RCD-operated circuit breaker (RCBO) combining overcurrent and residual current protection in a single 18 mm wide module. Rated at 10 A with a 30 mA Type A residual current trip, it protects final circuits against overload, short-circuit, and earth faults — one device, one DIN-rail slot.
The 10 A rated current and C tripping characteristic mean this RCBO is sized for general-purpose final circuits — lighting, small appliances, socket outlets — where inrush from capacitive or motor loads is moderate. Type A detects pulsating DC fault currents from rectifiers or electronic loads, not just pure AC sine-wave faults — a requirement for circuits feeding switched-mode power supplies, LED drivers, or variable-speed drives. Breaking capacity is rated at 4.5 kA per EN 60898 and 5 kA per IEC 60947-2. The EN 60898 figure governs residential and commercial distribution boards; the IEC 60947-2 figure applies when the device is used in industrial switchgear.
Panel integration
Depth is 77 mm, installation depth 70 mm — verify enclosure depth against the gland plate or busbar shroud clearance. Mounting position any, so it can be installed vertically, horizontally, or inverted without derating the thermal trip. Supply cable can enter from top or bottom, which simplifies busbar routing in multi-row distribution boards.
