The 45 mm width matches a single modular device pitch, so it slots into a panel without stealing adjacent space. Screw terminals on the main circuit accept solid conductors from 0.5 mm² up to 6 mm² (stranded) and auxiliary wiring down to 0.5 mm² solid. Terminal torque and strip length follow standard practice — no oddball tooling needed. Breaking capacity is 100 kA at 240 V, 400 V, 500 V, and 690 V AC — that's a full-range rating, not a derated curve. The 100,000-cycle mechanical endurance on the main contacts means it outlasts the motor in a typical cyclic application. Operates from -20 °C to +60 °C ambient, stores and ships from -50 °C to +80 °C. Shock rated at 25 g for 11 ms — survives the rough ride to site and the occasional hammer blow near the panel.","metaTitle":"Siemens 3RV1021-0FA15-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-0FA15-ZW97 SIRIUS motor protection circuit breaker, 0.5 A continuous rating, Class 10 trip, 100 kA breaking capacity at 400 V.

The 3RV1021 series carries higher breaking capacity (100 kA across the voltage range) compared to the 3RV1011 series. Check the terminal wire ranges and the auxiliary contact configuration — the 3RV1021-0FA15-ZW97 uses a transverse auxiliary switch design with no factory-fitted auxiliary contacts (0 auxiliary contacts), so if the original spec relied on side-mounted auxiliaries, you'll need to add them separately."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RV1021-0FA15-ZW97","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/3RV1021-0FA15-ZW97 when reusing this data.
