What this MCCB delivers on the line
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. An undervoltage release (UVR) is built in, meaning the breaker trips if control voltage drops below the dropout threshold — common on safety circuits or emergency-stop chains where loss of control power must open the main feeder.
Sourcing and lifecycle reality
Rated insulation voltage is 800 V, which covers 690 V line-to-line systems with margin; power loss at full load is 27.5 W, a figure to factor into enclosure thermal calculations if the panel is densely packed. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C — suitable for unheated warehouses or outdoor cabinets in temperate climates.
Panel fit and dimensions
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. No communication function or ground-fault monitoring is included on this variant; it is a straight thermal-magnetic line-protection breaker with undervoltage release, so it is a fit for simple feeder or branch protection where no remote trip indication or GFCI is needed.
