SIRIUS 3RV1011-0GA10-0FJ0-ZX95 — Motor Protection Circuit Breaker, 0.63 A, Class 10
The Siemens SIRIUS 3RV1011-0GA10-0FJ0-ZX95 is a motor protection circuit breaker designed for the 0.63 A continuous current range, with a Class 10 trip characteristic that clears overloads before the motor windings overheat. Its 100 kA breaking capacity at 400 V AC means it can interrupt a bolted fault up to that level without upstream fuses needing to clear — useful for high-fault panels where selectivity matters. Rated insulation voltage is 690 V, surge voltage resistance is 6 kV. Phase failure detection is built in. Mounts on 35 mm DIN rail per EN 50022 via screw and snap-on; zero clearance required on the sides or backwards, so it packs tight in a crowded enclosure. Any mounting position is allowed. The front face carries an IP20 rating — safe for finger-probe access in a live panel. Terminals are screw-type, accepting solid and stranded conductors up to 2.5 mm² (or 2x 1.5 mm²), and AWG 18–14 for the main circuit. An auxiliary switch is present on this variant, so you can wire a status feedback to the PLC without an add-on block.
Sourcing & Lifecycle
The base variant 3RV1011-0GA10 (without the -0FJ0-ZX95 suffix) is the same motor protection breaker without the factory-fitted auxiliary switch. If the auxiliary contact is not needed for your application, that version drops into the same footprint without rewiring — same 45 mm width, same DIN rail mount, same terminal layout. The -1HA10 variant steps up to a higher current range; verify the motor FLA before substituting.
Panel Integration & Environment
Dimensions: 45 mm wide, 90 mm high, 81 mm deep. The 45 mm width matches a standard 2.5-module DIN rail footprint, so it occupies two 18 mm slots on a 35 mm rail. Zero side and zero backwards clearance means you can abut it against adjacent devices or the enclosure wall — no breathing gap needed. Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C. Shock rated at 25g for 11 ms — suitable for machine-mounted panels on presses or conveyors. Maximum operating altitude is 2 000 m without derating. Power loss at rated current in hot operating state is 5.5 W total, or 1.8 W per pole. Mechanical endurance of the main contacts is 100 000 cycles typical. Maximum switching frequency under AC-3 duty is 15 operations per hour.
