The overload protection (Ir) is adjustable from 56 A to 80 A via the ATAM dial, and the short-circuit protection (Ii) is set at 5 to 10 times the rated current In (80 A). This gives the specifying engineer a 400 A to 800 A magnetic trip window, which is typical for motor branch circuits or distribution feeders where inrush must be distinguished from a fault. For a BOM line that specifies this exact variant — 3VA1 frame, class H breaking capacity, TM240 trip, 80 A, with clamp terminals and two HQ auxiliary switches — the fit is confirmed by the order code itself. The clamp connection terminals accept copper or aluminum conductors without requiring lug kits, which saves panel space and installation time. The two integrated HQ auxiliary switches provide status feedback for remote monitoring or PLC inputs.","metaTitle":"Siemens 3VA1180-6EF36-0AC0 Circuit Breaker, 70kA @ 415V, 80A","metaDescription":"Siemens 3VA1180-6EF36-0AC0 IEC frame 160 circuit breaker, breaking capacity class H, Icu=70kA @ 415V, 3-pole, In=80A, TM240 overload protection.
