Siemens 3VA1010-2ED36-0CA0 — 100 A MCCB with TM210 Release
The Siemens 3VA1010-2ED36-0CA0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with a TM210 thermal-magnetic overcurrent release. It is a 3-pole unit configured for line protection, meaning it sits at the feeder or branch-circuit level in a distribution panel, not on a motor starter. The interrupting ratings climb to 52.5 kA at 240 V and 32 kA at 415 V, which gives solid headroom for high-fault service-entrance or sub-distribution applications. The TM210 release is a fixed thermal-magnetic type — no interchangeable trip units, no electronic adjustments. That keeps the part simple and repeatable for BOM consistency: once you set the panel schedule, the trip curve is locked. The undervoltage release (UVR) is integrated as standard, so the breaker drops open on loss of control voltage, which is common in emergency-stop or safety-disconnect chains.
Thermal Derating and Ambient Constraints
The 100 A rating holds flat from 40 °C through 50 °C. Above that, derating is gradual: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. If the panel ambient runs hot — say, next to a transformer or in a non-climate-controlled enclosure — the 70 °C derating to 90 A is the figure to size against. The operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C.
Physical Fit and Panel Integration
The MCCB measures 70 mm deep, 76.2 mm wide, and 130 mm high. The 76.2 mm width is a standard 3-pole MCCB footprint — it fits the usual DIN-rail or panel-mount cutout without surprises. No auxiliary contacts are included; if you need alarm or status signaling, the separate 3VA9608-0BB24 auxiliary trip block is the intended add-on.
