Siemens SENTRON 3VA1110-6EF32-0AE0 — 100 A MCCB with TM240 Release
Breaking capacity reaches 220 kA at 240 V AC, 154 kA at 415 V, and 121 kA at 440 V — enough headroom for high-fault installations where upstream transformers or parallel feeds push available short-circuit current above typical MCCB ratings. At 500 V and 690 V it still clears 17 kA, covering most 480 V and 600 V class industrial systems.
Current rating holds flat at 100 A from 40 °C through 50 °C, then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. That means in a 50 °C panel — common for enclosed switchgear — you still get full 100 A capability without oversizing the frame. Above 50 °C, every degree costs roughly 0.4 A; plan your continuous load accordingly. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a compact 3-pole footprint that fits standard 76.2 mm (3 in) wide panel cutouts.
Auxiliary Switching and Insulation Coordination
If you need those features, the 3VA1 platform offers modular accessories that snap onto the same frame.
