The Siemens 3RV1011-1GA20-ZW96 is a SIRIUS motor protection circuit breaker rated for 6.3 A continuous current with a CLASS 10 trip characteristic, meaning it will trip within 10 seconds at 7.2× rated current — the standard thermal-magnetic curve for protecting standard induction motors during startup. Power rating at 400 V is 2.2 kW, which matches a standard 3 kW frame motor on a 400 V supply (the breaker is sized for the motor FLA, not the motor nameplate kW).
Width is 45 mm, height 90 mm, depth 81 mm — a standard SIRIUS 3RV1 footprint that shares the same slot as the 3RV1011-1HA10 and 3RV1011-0HA10 siblings. Main circuit and auxiliary/control circuits both terminate through spring-loaded terminals. Solid wire accepted is 2x (0.25... 2.5 mm²); finely stranded with ferrule is 2x (0.25... 1.5 mm²). AWG equivalent for main contacts is 2x (24... 14). Touch protection against electrical shock is finger-safe, so the live busbars behind the front cover are protected from accidental contact during commissioning.
Substance prohibitance date is 01.01.2013, aligning with the original EU RoHS directive scope. The part is RoHS-compliant; REACH and UL documentation is available from Siemens on request. Shock resistance rated at 25g / 11 ms.
