Transformer-Protection Circuit Breaker, 0.8 A, Class 10
The Siemens 3RV6411-0HA10 is a SIRIUS circuit breaker for transformer protection, rated at 0.8 A operational current with a Class 10 trip characteristic. Rated 690 V AC at 50/60 Hz, 3-pole, Size S00, with a thermal-magnetic overload release and magnetic short-circuit trip. The 6 W typical power loss stays within the thermal budget of a crowded DIN-rail enclosure. Mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, in any position. Clearance requirements: 50 mm above and below, 30 mm at the sides, zero forward or backward — so it fits tight against the back panel.
Integration & Wiring
Screw-type terminals on top and bottom accept 2×(0.75–2.5 mm²) solid/stranded or 2×4 mm², or 2×(18–12 AWG) solid. Torque to 0.8–1.2 N·m. Finely stranded with ferrule: 2×(0.5–1.5 mm²) or 2×(0.75–2.5 mm²). Dimensions: 45 mm wide, 97 mm high, 96 mm deep — fits standard S00 footprint. Operating temperature -20 to +60 °C, storage -50 to +80 °C, humidity 10–95%. Shock resistant to 25 g / 11 ms per IEC 60068-2-27; surge voltage withstand 6 kV. Installation altitude up to 2000 m.
