Its CLASS 10 trip characteristic means it clears overloads within 10 seconds at 7.2× rated current — fast enough to keep a motor winding below thermal damage threshold during a stall or jam. Breaking capacity is 50 kA at 400 V AC, stepping up to 100 kA at 240 V and dropping to 3 kA at 500 V, 2 kA at 690 V. That 50 kA at 400 V is the number that matters for most European industrial panels — it handles fault currents from a typical 630 kVA transformer secondary without needing an upstream fuse or current-limiting reactor. Spring-loaded terminals on both the main and auxiliary/control circuits accept 2x (0.25 … 2.5 mm²) solid or 2x (0.25 … 1.5 mm²) finely stranded with ferrules. No screwdriver torque check needed — the cage clamp holds repeatable contact force shot after shot. Width is 45 mm, height 90 mm, depth 81 mm. Zero clearance required at the sides or rear — 0 mm backwards, 0 mm at the side — so it nests tight against adjacent devices on the 35 mm DIN rail per EN 50022. Screw and snap-on mounting; any orientation is permitted. The housing is rated for shock at 25g / 11 ms, so it holds calibration in a machine-tool environment with frequent axis acceleration.","metaTitle":"Siemens 3RV1011-1JA20 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV1011-1JA20 SIRIUS motor protection circuit breaker, 10 A continuous, CLASS 10 trip, 50 kA at 400 V.
