It's a current-production part, so no last-time-buy scramble. Rated In = 20 A with an adjustable thermal overload (Ir) from 14 A to 20 A, so you dial in the continuous current to match the conductor or load without swapping the breaker body. The magnetic short-circuit pickup is fixed at 16 × In (320 A), which is a standard motor-start or distribution curve — not a high-selectivity setting, but fine for branch protection where you want fast clearing on bolted faults. The TM220 trip unit is thermal-magnetic, line-protection grade; no electronic adjustments beyond the Ir dial. ## Deployment context This breaker lands in a panelboard or enclosure on a DIN rail or mounting plate — the frame 160 footprint is standard across the 3VA1 family. The nut keeper kit is a panel-builder detail: it holds the busbar or cable lug nuts captive during assembly, saving time on a crowded gland plate.","metaTitle":"Siemens 3VA1120-6EE42-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1120-6EE42-0AA0-ZD00 IEC frame 160 circuit breaker, 70kA @ 415V, 4-pole, 20A, TM220.
