It carries a TM240 thermal-magnetic trip unit with an adjustable overload protection band from 112 A to 160 A (Ir) and a short-circuit pickup (Ii) adjustable from 5 to 10 times the rated current In. The thermal element handles sustained overloads; the magnetic element clears hard shorts. The 160 A frame gives headroom for a 150 A continuous load without nuisance tripping on motor inrush. The built-in undervoltage release (UVR) operates on 24 V DC — if the control voltage drops, the breaker trips. That is standard for emergency-stop or safety-shutdown circuits where loss of control power must open the main feeder. This breaker uses clamp (lug) connections, so it lands directly on busbars or cable lugs in a distribution panelboard or switchboard. The 3VA1 frame is a standard IEC form factor for DIN-rail or panel-mount enclosures — it occupies the same footprint as other 160 A frame breakers in the 3VA family, making it a drop-in replacement for an existing 3VA1 unit without re-drilling the backplate.","metaTitle":"Siemens 3VA1116-3EF36-0BH0 Circuit Breaker, 160A, 25kA @ 415","metaDescription":"Siemens 3VA1116-3EF36-0BH0 IEC frame 160 circuit breaker, 25kA breaking capacity at 415V, 160A thermal-magnetic protection, UVR 24V DC, auxiliary switches.
