This breaker is designed for motor protection duty, combining a thermal overload element for sustained overcurrents and a magnetic short-circuit trip. The S00 frame measures 45 mm wide, 90 mm high, and 75 mm deep, with 20 mm clearance required above and below the unit and 9 mm at the sides — no extra space needed in front or behind. That keeps the footprint tight on a crowded DIN rail. The breaker snaps onto standard 35 mm rail and accepts screw-clamp wiring; the Pozidriv #2 screw terminals torque to 0.8–1.2 N·m for both main and auxiliary contacts. At full load the breaker dissipates 9.25 W total (3.1 W per pole) in the hot operating state — a factor to check when calculating enclosure heat rise in a sealed panel.","metaTitle":"Siemens 3RV1011-1KA10-ZI45 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1011-1KA10-ZI45 motor protection circuit breaker, size S00, 12.5 A rated current, adjustable 9-12.5 A thermal overload, CLASS 10 trip, screw terminals.

The difference is the current range: the 1HA10 adjusts 5.5–8 A while this 1KA10 adjusts 9–12.5 A. If the load current falls within 9–12.5 A, the 1KA10 is a direct mechanical fit — no rewiring or panel modification needed."},{"question":"Where can I buy 3RV1011-1KA10-ZI45?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution channels.
