The Siemens SIRIUS 3RV1011-0FA10-0FJ0-ZX95 is a motor-protective circuit breaker rated at 0.5 A continuous current with CLASS 10 trip characteristics. It delivers 100 kA breaking capacity at 400 V AC, meaning it can safely interrupt fault currents up to that level without cascading upstream — critical for panel selectivity in high-fault installations. Phase failure detection is built in, so a lost phase trips the breaker before the motor burns. The 45 mm width and 81 mm depth fit standard DIN-rail enclosures; screw and snap-on mounting onto 35 mm rail per DIN EN 50022 simplifies panel integration.
Installation & Environment
Mount in any position on 35 mm DIN rail per DIN EN 50022. Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C. IP20 on the front means the breaker is touch-safe but not sealed against moisture — suitable for dry indoor panels, not washdown zones. Shock-rated to 25g for 11 ms, so it holds up in applications with moderate vibration.
Termination & Wiring
Main circuit terminals are screw-type, accepting solid or stranded conductors: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²), with AWG equivalents 2x (18 to 14). Finely stranded with core end processing uses the same ranges. No auxiliary contacts are included (0 for auxiliary contacts), but the breaker has an auxiliary switch option (yes).
