The Siemens SIRIUS 3RV1011-1AA10-ZW98 is a motor-protection circuit breaker with a Class 10 trip characteristic, meaning it disconnects within 10 seconds at 7.2× the thermal setting — fast enough to protect standard induction motors during a stall or locked-rotor event without nuisance tripping on normal start-up. The 100 kA breaking capacity at 400 V means it safely interrupts fault currents up to that level without cascading upstream; at 690 V the rating drops to 2 kA, so verify the available fault current at the installation point if running on a 690 V line. No ground-fault detection on this variant.
Clearance: 20 mm upwards, 20 mm downwards, 9 mm at the side, zero forwards or backwards. Screw-type terminals on the main circuit accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²). Torque spec for the M3 main-contact screws is standard — use a 5.5 mm nut driver. Backup fuse requirements: at 400 V and above, fit a gL/gG 20 A fuse upstream; at 240 V none is required.
