Breaking capacity reaches 100 kA at both 240 V and 400 V AC, dropping to 3 kA at 500 V and 2 kA at 690 V — so on a 400 V line this breaker handles fault currents large enough to sit downstream of most distribution transformers without needing a current-limiting upstream device. Spring-loaded terminals on both main and auxiliary circuits accept 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule. IP20 finger-safe protection on the front face; suitable for enclosed panel use where operators might reach in during maintenance. RoHS compliance date marked as 01.01.2013 — the part meets the EU RoHS directive effective from that date. Surge voltage resistance rated at 6 000 V, which covers the impulse withstand for industrial control panels per IEC 60947.","metaTitle":"Siemens 3RV1011-1EA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1011-1EA20 SIRIUS motor protection circuit breaker, 4 A rated current, CLASS 10 trip, 100 kA breaking at 400 V.
