That means you size the breaker for the load, not the panel temperature. At 690 V AC it still clears 3 kA. No voltage trigger, no ground-fault monitoring, no communication function — this is a straight distribution breaker, not a power monitor. ## Panel fit — dimensions and mounting The IP40 front protection means it's fine inside a closed enclosure — no special sealing needed for the operator face.","metaTitle":"Siemens 3VA2040-6HL36-0AA0 SENTRON MCCB, 40 A, 3-pole, 242 k","metaDescription":"Siemens SENTRON 3VA2040-6HL36-0AA0 molded case circuit breaker, 40 A continuous, 3-pole, ETU320 release, 242 kA at 240 V.
