That Icu figure means it can safely interrupt a fault current up to 70,000 A without welding or rupturing — critical for high-fault installations like large motor control centers or transformer secondaries where the available short-circuit current is substantial. The thermal-magnetic trip unit (TM240, ATAM) provides adjustable overload protection (Ir) from 56 A to 80 A, and short-circuit protection (Ii) set at 5 to 10 times the rated current In (80 A). This adjustability lets you fine-tune the overload pickup to match the cable or load ampacity, and set the magnetic instantaneous threshold to ride through motor inrush without nuisance tripping. ## Integrated accessories and deployment context Factory-fitted with a shunt trip (STL) rated 220-250 V DC and 208-277 V AC, plus two auxiliary switches (HQ) and one trip alarm switch (HQ). The shunt trip allows remote tripping from an E-stop or safety PLC; the auxiliary and alarm contacts feed status back to the control system. The nut keeper kit is included, which retains the terminal nuts during high-vibration installation — a small detail that saves time on a panel build. This breaker mounts on a DIN rail or can be screw-fixed to a backplate. In a panel, the 160 A frame size occupies roughly the same footprint as a standard 3VA1 three-pole unit; plan for adequate finger-duct clearance above and below for the shunt trip wiring and auxiliary cable looms.","metaTitle":"Siemens 3VA1180-6EF32-0KH0 Circuit Breaker, 70kA @ 415V, 80A","metaDescription":"Siemens 3VA1180-6EF32-0KH0 IEC frame 160 circuit breaker, 70kA breaking capacity at 415V, 80A thermal-magnetic protection.
