Breaking capacity is 440 kA at 240 VAC, 242 kA at 415 V and 440 V, 154 kA at 500 V, and 17 kA at 690 V. That 440 kA figure at 240 V is the headline number, but for a 400 V-class panel the 242 kA at 415 V is the one that governs the fault-withstand decision against the upstream transformer. Maximum power loss is 80.1 W — a figure to include in the enclosure thermal budget when grouping several breakers in a single panel. ## Peer comparison note Compared to the smaller-frame 3VA1112-5EE32-0AA0, this 3VA1332-7EF32-0AA0 carries a higher continuous current (320 A vs the 1112's lower rating) and a TM240 release instead of a lower TM setting. The 3VA1110 variants (5ED32-0AA0, 5ED36-0AA0) are also 3-pole but with lower ampacity and different trip curves. Panel cutout dimensions differ between the 3VA1 frame sizes, so a swap between the 1332 and the 1112 series requires verifying the mounting footprint and bus-bar spacing.","metaTitle":"Siemens 3VA1332-7EF32-0AA0 SENTRON MCCB, 320 A, 440 kA at 24","metaDescription":"Siemens 3VA1332-7EF32-0AA0 SENTRON molded case circuit breaker, 3-pole, TM240 release, 320 A at 40 °C, 440 kA breaking capacity at 240 VAC.
