Interrupting capacity is substantial: 440 kA at 240 V AC, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. That high fault-clearing ability means it can be installed close to large transformers or high-capacity busways without worrying about the breaker failing to clear a bolted fault — the arc extinguishes inside the molded case, not upstream. The IP40 front protection keeps dust and accidental contact out of the trip mechanism, but it's not rated for washdown — keep it in a dry enclosure. The 105 mm width (4.13 in) means it occupies three pole spaces in a typical MCCB lineup — verify your busbar spacing before committing the drill pattern.","metaTitle":"Siemens 3VA2140-8HL36-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU32","metaDescription":"Siemens SENTRON 3VA2140-8HL36-0AA0 molded case circuit breaker, 40 A continuous, 3-pole, ETU320 electronic trip, 440 kA at 240 V.
