The Siemens SENTRON 3VA1010-4ED42-0DA0 is a 4-pole molded case circuit breaker (MCCB) rated 100 A at 40 °C, built for line protection in distribution panels. It carries a TM210 thermal-magnetic trip unit — the '210' indicates the fixed thermal pickup and magnetic adjustment range — and includes an integrated undervoltage release (UVR) for coordinated load shedding or safety disconnects.
Breaking capacity and selectivity
This MCCB delivers 121 kA interrupting capacity at 240 V, dropping to 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Those figures cover most industrial service-entrance and sub-distribution fault levels; the 690 V rating is useful for 600 V class Canadian or mining installations where the full kA is still needed. The 800 V rated insulation voltage (Ui) supports use in 690 V systems with margin, and the 100 A frame at 40 °C holds flat through 50 °C — no derating needed up to that point. Above 55 °C it steps down to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C.
Panel fit and integration
Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth — a compact 4-pole footprint that fits standard MCCB mounting plates in SENTRON distribution boards. The 27.5 W maximum power loss should be factored into enclosure thermal calculations, especially in sealed or high-ambient cabinets. Operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C. No communication module or ground-fault monitoring is fitted on this variant; the UVR is the only auxiliary release.
