Its CLASS 10 trip characteristic means it will disconnect within 10 seconds at 7.2× the set current — the standard for protecting standard induction motors during locked-rotor starts. The adjustable overload release spans 0.9 to 1.25 A, with a rated operating current of 1.25 A and a rated power of 370 W at 400 V. ## Integration Notes Power loss at rated current in hot operating state is 5.5 W total, 1.8 W per pole — factor that into enclosure thermal calculations when grouping multiple breakers. Screw-type terminals on top and bottom accept solid or stranded wire; torque to 0.8–1.2 N·m for main contacts.","metaTitle":"Siemens 3RV1011-0KA15-ZI45 SIRIUS Motor Protection CB, CLASS","metaDescription":"Siemens SIRIUS 3RV1011-0KA15-ZI45 motor protection circuit breaker, CLASS 10, adjustable 0.9-1.25 A overload, 1.25 A rated, S00 size, DIN rail mount.
