The 40 A continuous rating and CLASS 10 trip characteristic mean it handles inrush on standard induction motors up to about 18.5 kW at 400 V and trips fast enough to protect the motor during a stall or jam — not so fast that nuisance trips plague you on startup. ## Breaking capacity and fault handling This breaker is rated to interrupt 100 kA at 240 V, 50 kA at 400 V, 12 kA at 500 V, and 6 kA at 690 V. Those numbers tell you it can handle a dead short on a high-capacity transformer without welding its contacts shut — a key selectivity consideration for the site electrical engineer. The 690 V rated value means it's fine on 480/600 V systems common in North America, not just 400 V European grids. Width is 70 mm, depth 174 mm, height 165 mm — that's a standard three-pole MCCB footprint, so it'll fit existing panel cutouts. Terminal wiring accepts solid 2x (2.5 to 16 mm²) or stranded 2x (10 to 50 mm²) and 1x (10 to 70 mm²), with AWG equivalents listed for the main contacts. The screw-type box terminals are familiar to any panel wireman; no special crimp tools needed. Mounting position is any, which helps when you're shoehorning this into a tight gland plate layout. ## Environmental toughness That's enough for unheated warehouses or hot Texas pump houses. Shock rated at 25g for 11 ms — it'll stay latched through a forklift bump or a compressor start jolt. ## Power dissipation and auxiliary options Dissipates 23 W in hot operating state (7.7 W per pole). The product extension for auxiliary switches is supported, so you can add a remote status contact for the PLC or a shunt trip for emergency-stop circuits.","metaTitle":"Siemens 3RV1041-4FA10-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1041-4FA10-ZX95 SIRIUS motor protection circuit breaker, 40 A continuous, CLASS 10 trip, 50 kA at 400 V.
