The Siemens SENTRON 5SV9313-7NK06 is a 2-pole (1P+N) RCD-operated circuit breaker — an RCBO — combining overcurrent and residual-current protection in a single 18 mm-wide module. Rated 6 A at AC with tripping characteristic C and Type A residual-current sensitivity, it breaks fault currents up to 4.5 kA. The instantaneous design clears short-circuits fast.
Ratings and thermal derating
Above that, the continuous current must be derated: 5.64 A at 40 °C, 5.46 A at 45 °C, 5.22 A at 50 °C, and 5.04 A at 55 °C. Ambient operating range is -25 to +40 °C; storage range is -40 to +75 °C. Mounting position is unrestricted, so it fits horizontal or vertical DIN-rail layouts without further derating.
Installation and wiring
The module occupies one width unit (18 mm) on a DIN rail, with an installation depth of 70 mm and overall depth of 77 mm. Terminals accept solid or stranded conductors from 0.75 to 16 mm². Supply can enter from either top or bottom, simplifying panel layout. Touch protection is built in. The IP20 rating applies only when the distribution board is installed and conductors are connected — not a standalone ingress rating.
