The screw-type terminals on top and bottom accept solid or stranded conductors up to 2.5 mm², with a tightening torque of 0.8 to 1.2 N·m. For a panel-builder, this means the breaker fits into the same DIN-rail footprint as a contactor of the same S00 frame, allowing a direct bus-bar link without extra adaptors. ## Integration with S00 contactors Power dissipation at rated current is 5.5 W total (1.8 W per pole in hot state), which is low enough that no forced cooling is needed in a standard IP20 enclosure.","metaTitle":"Siemens 3RV1011-0KA10-ZI45 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1011-0KA10-ZI45 motor protection circuit breaker, size S00, CLASS 10, adjustable overload release 0.9...1.25 A, screw terminals, current lifecycle stage.

The key difference is the overload setting range: the -0GA10 covers 0.45 to 0.63 A, while the -0KA10 covers 0.9 to 1.25 A. If your motor's full-load current falls within 0.9 to 1.25 A, the -0KA10 is the correct fit; the -0GA10 would be undersized and cannot be adjusted up to cover that range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV1011-0KA10-ZI45","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RV1011-0KA10-ZI45 when reusing this data.
