Mounting position is any — horizontal, vertical, upside-down, whatever the panel layout needs. The IP20 front face means it's finger-safe when installed in a closed panel. Spring-loaded terminals accept 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule. For AWG, that's 2x (24... 14). No torque spec to chase — just strip to 8-10 mm and push in. Shock rated at 25 g for 11 ms — survives rough handling during shipping. RoHS compliance date is 01.01.2013 — it's been RoHS-compliant since then. The part carries finger-safe touch protection and surge voltage resistance at 6 000 V.","metaTitle":"Siemens 3RV1011-1HA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens SIRIUS 3RV1011-1HA20 motor protection circuit breaker, 8 A continuous, CLASS 10 trip, 50 kA at 400 V.
