What this MCCB delivers
The Siemens SENTRON 3VA1032-3ED32-0AC0 is a 3-pole molded case circuit breaker rated for 32 A continuous current, with a TM210 thermal-magnetic release that handles both overload and short-circuit protection in a single package. Breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — enough headroom for most industrial distribution panels where fault currents can spike during a bolted fault. The 32 A rating holds steady from 40 °C up to 50 °C, then derates gradually to 28.8 A at 70 °C — meaning you can pack it into a warm enclosure without losing much capacity. Two built-in auxiliary switches (HQ type) provide status feedback to a PLC or indicator lamp without needing an add-on module.
Panel fit and environment
At 76.2 mm wide, 130 mm tall, and 70 mm deep, this breaker fits standard 3-pole MCCB footprints — no surprises when swapping into an existing SENTRON or third-party panel. Front face carries IP40 protection, so it's fine for dry indoor panels but not for washdown zones or outdoor cabinets without a secondary enclosure. Operating range spans -25 °C to 70 °C, storage from -40 °C to 80 °C — covers unheated warehouses and most plant-floor conditions.
