The rated insulation voltage Ui is 800 V, confirming the breaker's internal insulation system is rated for 800 V phase-to-phase, so it's suitable for 480/277 V and 600/347 V North American systems as well as 400 V and 690 V IEC systems. ## Thermal derating and the real-world current limit At 55 °C it drops to 96 A, at 60 °C to 94 A, at 65 °C to 92 A, and at 70 °C to 90 A. If the breaker is mounted in a hot enclosure (near a drive, transformer, or in a non-ventilated cabinet), use the 90 A figure at 70 °C as your continuous load limit. The maximum power loss is 75 W at rated current; that's the heat the breaker dumps into the enclosure, so factor it into the panel thermal calculation. ## Release, aux contacts, and integration notes The overcurrent release is the ETU310M, an electronic trip unit with LSI curves (long-time, short-time, instantaneous) — adjustable, so you can coordinate selectively with downstream breakers. The auxiliary contact configuration is 1 auxiliary switch + 1 trip alarm switch HP, which gives you one N.O./N.C. set for status feedback (breaker open/closed) and one dedicated to signaling a trip event.","metaTitle":"Siemens SENTRON 3VA2110-7MS32-0AG0 MCCB, 100 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2110-7MS32-0AG0 molded case circuit breaker, starter protection version, 3-pole, 100 A rated continuous current, 330 kA breaking capacity at 240 V.
