Short-circuit ratings — the real story
The 3RV2311-1CC10 carries a 100 kA SCCR at 240 V, 400 V, and 500 V — that's the interrupting capacity at the line side, meaning it can clear a bolted fault up to 100,000 A without welding its contacts or venting plasma into the panel. For selective coordination with upstream fuses, the manufacturer specifies maximum gL/gG fuse ratings: 25 A at 400 V and 500 V, 20 A at 690 V — these are the fuse sizes that let the breaker trip first on a downstream fault while the fuse holds.
Motor horsepower and current ratings
The breaker is rated for motor loads: 0.5 hp at 200/208 V and 220/230 V, 1 hp at 460/480 V, and 1.5 hp at 575/600 V — these are the NEMA horsepower ratings that tell you which motor frame this breaker can protect. At 480 V the continuous current rating is 2.5 A, and the same at 600 V — that's the thermal-magnetic pickup for overload protection, not the short-circuit rating.
Panel fit and clearances
The 3RV2311-1CC10 measures 97 mm deep, 45 mm wide, and 97 mm tall — the 45 mm width is a standard 2.5 module pitch on DIN rail, so it occupies two adjacent 18 mm slots plus a bit. Terminals are M3 screw-type for the main circuit, accepting 2x 0.75 to 2.5 mm² solid or stranded, or 2x 4 mm² — standard for control panel wiring, no special crimp tools needed.
Environmental and storage specs
Rated operational voltage spans 20 to 690 V, covering most low-voltage industrial systems worldwide.
