The Siemens SENTRON 3VA1032-4ED36-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated for a continuous current of 32 A, with a TM210 thermal-magnetic overcurrent release. It's built for line protection in distribution panels, sized to fit a 76.2 mm wide footprint on a DIN rail or panel mount. The 121 kA breaking capacity at 240 V means it can safely interrupt very high fault currents at that voltage — critical for installations close to the transformer where available fault current is high. At 415 V the interrupting rating drops to 75.6 kA, still well above typical distribution levels, and at 690 V it holds 11.9 kA. The thermal derating curve is published: full 32 A up to 50 °C ambient, then steps down to 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. If the panel runs hot, you need to account for that reduction — the breaker will trip earlier if you load it to the full 32 A above 50 °C.
Integration & Mounting
At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits standard SENTRON panel cutouts and DIN-rail spacing. The 3-pole form factor with three auxiliary switches HQ gives you status feedback for remote monitoring or interlocking — useful when the breaker feeds a motor control center or a critical process line. Rated insulation voltage is 800 V, so it's suitable for 690 V systems with margin. Front protection is IP40 — fine for a clean indoor panel, but not for washdown or outdoor exposure. No undervoltage release, no ground-fault monitoring, no communication module on this variant; it's a straight thermal-magnetic line-protection breaker.
