The Siemens SENTRON 3VA1010-2ED36-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 100 A continuously at 40 °C ambient with no derating needed up to 50 °C — above that it steps down to 98 A at 55 °C and 91 A at 70 °C, so a warm panel enclosure still leaves headroom for the full load current. Breaking capacity is 52.5 kA at 240 V, 32 kA at 415 V, and 7.5 kA at 690 V — the 415 V figure is the one that governs most European industrial distribution panels, and it clears faults well above typical transformer-fed bus ratings. The TM210 overcurrent release is a thermal-magnetic design fixed at 100 A, so it is a straight 100 A frame — no interchangeable rating plug, which simplifies BOM but locks the trip threshold.
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or screw-mount panel layouts without requiring a sub-panel adapter.
