The CLASS 10 trip matches standard motor thermal damage curves; a slower CLASS 20 or 30 would let the motor cook longer during a stall. No ground fault detection, so that must be handled separately if required. The auxiliary contact ratings are 1 A at 24 V and 1.5 A at 230 V — these are the signal-level contacts for the PLC or control relay, not the main power path. Main circuit terminals are M3 screw-type, accepting 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²) solid or stranded — standard for a 0.2 kW motor at 230 V or 1 hp at 460/480 V. ## Mechanical integration and clearances The 3RV2111-0KA10 measures 65 mm wide × 97 mm high × 97 mm deep — a compact footprint that fits standard 65 mm-wide DIN-rail slots. For thermal derating and arc-flash clearance, allow 50 mm upwards and 50 mm downwards, and 30 mm at the sides. Zero clearance forwards and backwards means it can sit flush against a panel backplate or door. The 3RV2111-0KA10 is listed as current production. For volume or scheduled buys, submit an RFQ for firm lead times and quantity breaks.","metaTitle":"Siemens 3RV2111-0KA10 SIRIUS Motor Protection Circuit Breake","metaDescription":"Siemens 3RV2111-0KA10 SIRIUS motor protection circuit breaker.
