It carries a TM240 thermal-magnetic trip unit — the thermal element adjustable from 56 to 80 A, the magnetic pickup fixed at 5 to 10 times In. That means for a motor feeder or distribution panel, you set the Ir dial to match the load current, and the instantaneous trip stays above inrush so nuisance trips don't pull you out of a shift. The shunt trip lets a remote pushbutton or safety relay drop the breaker under load — useful for emergency-stop circuits or remote disconnect in a pump house. The auxiliary switches track the breaker position for PLC status inputs; the alarm switch signals only when the breaker trips on fault, not when it's manually opened. It's not a high-rupturing-capacity main; it's a feeder or branch breaker. The clamp (lug) connection accepts copper or aluminum conductors, typical for panel-board and motor-control-center wiring. The 3VA1 frame is a compact IEC design — it fits the standard DIN-rail or panel-mount footprint without eating up enclosure space. ## Integration notes The shunt trip coil draws power from a separate control circuit — verify the supply voltage matches the 12–30 V DC or 24 V AC rating before wiring. The auxiliary switches and alarm switch are factory-installed; no field-add kit needed. For coordination studies, the TM240 trip curve is published in the Siemens selectivity manual; the thermal adjustment band (56–80 A) lets you dial in the exact overload protection for the downstream load without changing the breaker.","metaTitle":"Siemens 3VA1180-3EF36-0HH0 Circuit Breaker, 80A, 25kA @ 415V","metaDescription":"Siemens 3VA1180-3EF36-0HH0 IEC frame 160 MCCB, 3-pole, 80A, 25kA breaking capacity at 415V.
