The thermal-magnetic trip unit is a TM240 ATAM, set at In = 40 A, with adjustable overload protection (Ir) from 28 A to 40 A and fixed short-circuit protection (Ii) at 5 to 10 times In. The Ir adjustment lets you fine-tune the continuous current rating to match the downstream cable or load without swapping the breaker body. This variant includes a nut keeper kit and is designated for a DC Power OEM in China — the nut keeper prevents hardware loosening under vibration in power-conversion cabinets. The breaker itself is standard 3VA1 platform, so it mounts in the same Siemens panelboard and distribution board footprints as other 3VA frame-160 units.","metaTitle":"Siemens 3VA1140-6EF32-0AA0-ZD00 Circuit Breaker, 70kA @ 415V","metaDescription":"Siemens 3VA1140-6EF32-0AA0-ZD00 IEC frame 160 circuit breaker, 70kA breaking capacity at 415V, 40A TM240 thermal-magnetic trip, current production.
