The interrupting ratings climb to 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 — meaning this breaker handles high-fault-capacity main feeders without cascading upstream devices. At 55 °C the continuous rating begins to derate to 385 A, dropping to 340 A at 70 °C, so panel ambient temperature directly governs the usable ampacity. The breaker measures 248 mm high, 138 mm wide, and 110 mm deep — a standard SENTRON 3VA frame size that fits existing 3VA panel cutouts and busbar arrangements. ## Panel fit and compliance documentation The 3VA2340-7HN32-0KA0 drops into the standard SENTRON 3VA footprint — same 138 mm width and 248 mm height as the 3VA2163-8HM32-0AA0, so a panel already cut for that frame accepts this breaker without rewiring or busbar modification.","metaTitle":"Siemens 3VA2340-7HN32-0KA0 SENTRON MCCB, 400 A, 3-Pole, 330","metaDescription":"Siemens SENTRON 3VA2340-7HN32-0KA0 molded case circuit breaker, 400 A rated, 3-pole, 330 kA interrupting at 240 V.
