Breaking capacity runs 100 kA at 240 V AC, 50 kA at 400 V AC, 3 kA at 500 V AC, and 2 kA at 690 V AC (–), which covers most industrial distribution panels downstream of a transformer.
Accepts 2x (0.25 … 2.5 mm²) solid or 2x (0.25 … 1.5 mm²) finely stranded with ferrule. Width is 45 mm, height 90 mm, depth 81 mm. Zero clearance needed at the back or sides. IP20 on the front — fine inside a closed panel, not for washdown zones.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no fixed stock or price is published here.
Both are 45 mm wide SIRIUS breakers with the same DIN rail footprint and spring-terminal format, so the mechanical fit is identical. The key difference is the trip rating — 3RV1011-1HA10 is a lower-current variant. Verify the motor FLA matches the 12 A continuous rating of this unit before swapping.
RoHS compliance is confirmed effective 01.01.2013. The product is designed to IEC/EN 60947 standards as a SIRIUS motor protection circuit breaker. UL and CSA listings are standard for this series, though specific file numbers are not in this listing.
