The interrupting ratings are the headline: 242 kA at 240 V, 187 kA at 415 V and at 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. That matters for coordination studies: you can shape the trip curve to match downstream devices without oversizing the main. Front IP40 protection means it's fine for indoor panel use but not washdown zones. Maximum power loss is 1.6 W, so heat buildup in a dense panel is negligible — no special ventilation required for this position. The design accepts a motor drive option, so remote trip or close via a PLC output is possible without a separate contactor.","metaTitle":"Siemens 3VA2140-6HN32-0AA0 SENTRON MCCB, 40 A, 242 kA at 240","metaDescription":"Siemens SENTRON 3VA2140-6HN32-0AA0 molded case circuit breaker, 40 A, 3-pole, ETU350 release, 242 kA at 240 V.
