The interrupting ratings tell you where this breaker can sit in the fault-current hierarchy: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. The trip indicator is present, undervoltage release is not, and there is no ground-fault monitoring or communication function on this variant. The basic switch it builds on is order code 3VA2340-7HL32-0AA0. At 110 mm deep, 138 mm wide, and 248 mm tall, this MCCB fits the standard SENTRON 3VA mounting footprint. The 138 mm width across three poles is the dimension to check against your existing busbar spacing or DIN-rail adapter. Depth of 110 mm leaves clearance for rear-connected busbars in a typical distribution panel. Maximum power loss is 96 W at rated current — account for that heat in your enclosure ventilation calculation, especially if the breaker is enclosed in a low-volume panel with other heat sources.","metaTitle":"Siemens 3VA2340-7HL32-0AG0 SENTRON MCCB, 400 A, 3-Pole, 110","metaDescription":"Siemens 3VA2340-7HL32-0AG0 SENTRON molded case circuit breaker, 400 A continuous, 3-pole, line protection. 330 kA at 240 V.
