That matters when the panel runs hot and you need the breaker to hold without nuisance tripping. The 3VA series is Siemens' current-generation MCCB platform. If the BOM calls for a 320 A 4-pole with a fixed thermal-magnetic curve, this is a direct fit. Dimensions: 248 mm tall, 184 mm wide, 110 mm deep. Keep it inside the enclosure, not on the door. That's not trivial — if you're packing a dozen of these in a panel, factor that heat into the ventilation budget. The storage spec governs handling and shipping, not running. ## What it doesn't have — and why that's fine This is a plain-vanilla line-protection MCCB. If you need adjustable trip curves or remote monitoring, look at the 3VA electronic-trip variants. But if the spec says '320 A, 4-pole, thermal-magnetic, line protection,' this is the exact part.","metaTitle":"Siemens SENTRON 3VA1332-5GF42-0AA0 MCCB, 320 A, 4-pole, TM24","metaDescription":"Siemens SENTRON 3VA1332-5GF42-0AA0 MCCB, 320 A rated, 4-pole, TM240 thermal-magnetic release.
