Siemens SENTRON 3VA1010-2ED32-0AD0 — 100 A MCCB, line protection, active production
The Siemens 3VA1010-2ED32-0AD0 is a SENTRON 3-pole molded case circuit breaker rated for line protection, carrying 100 A continuously at 40 °C and breaking up to 52.5 kA at 240 V. Rated breaking capacity drops with system voltage: 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That 7.5 kA at 690 V is the floor — useful for 690 V industrial networks where fault current is typically lower than at 240 V. The 100 A rating holds through 50 °C; above that it derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard SENTRON 3VA footprint that mounts on a DIN rail or panel-mount adapter.
With a TM210 release and 52.5 kA interrupting at 240 V, this breaker coordinates downstream with SENTRON 3VA1 and 3VA2 series for selective tripping on most feeder-to-branch ratios. The 25 W max power loss matters for enclosure thermal calculations — in a sealed panel with multiple breakers, sum the losses and check the temperature rise against the 70 °C max operating ambient.
