Interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V, and still 121 kA at 500 V — that's high-fault headroom for a 400 A frame, meaning it handles a hard bolted fault without upstream coordination headaches. ## Line protection design with auxiliaries The basic switch inside is order code 3VA2440-6HN32-0AA0; this -0KL0 suffix adds the auxiliary and alarm package. It ships with a voltage trip indicator and a mechanical trip indicator — no guesswork when you walk the route and see a flagged handle. Footprint is 138 mm wide by 248 mm tall by 110 mm deep — that's 5.43 by 9.76 by 4.33 inches.","metaTitle":"Siemens 3VA2440-6HN32-0KL0 SENTRON MCCB, 400 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2440-6HN32-0KL0 molded case circuit breaker, 400 A continuous, 3-pole, 242 kA at 240 V.
