Its interrupting capacity hits 75.6 kA at 240 V and 9 kA at 415 V — that's serious fault-clearing headroom for a single-pole device in a 240 V line-to-neutral or DC circuit.
At 70 mm deep, 25.4 mm wide, and 130 mm tall, this breaker fits standard 1-inch-per-pole MCCB panel cutouts — the same footprint as most SENTRON 3VA single-pole units. The 75.6 kA interrupting rating at 240 V is well above typical residential or light commercial available fault current (often 10–22 kA), so this breaker gives you selectivity headroom without needing a current-limiting upstream device. At 415 V it still clears 9 kA, which covers most industrial panel secondary faults. The TM210 release combines a thermal bimetal for overload protection (adjustable via the rating plug) with a fixed magnetic instantaneous trip set at 320 A — that's 10x the 32 A rating, so it rides through motor inrush without nuisance tripping. Power loss is 3.53 W max, negligible for panel thermal budgeting.
Where it goes — deployment context
As a line-protection MCCB (Product version: Line protection), this is the primary breaker for a branch circuit feeding a load center, a distribution panel, or a motor control center bucket. Rated for 125 V DC maximum, it can also serve as a DC branch breaker in battery banks or solar combiner boxes — useful if you're mixing AC and DC loads in the same panel.
Compared to the 3VA2025-8HN42-0AA0, which is a 2-pole 25 A unit with a different release curve, this 1-pole 32 A version with the TM210 release is the right choice when you need a single-pole branch breaker with a higher continuous rating but still want the fixed 320 A magnetic trip for motor or transformer loads. The 3VA2025-8HN42-0AA0 won't drop in without rewiring because it's 2-pole (wider footprint) and has a different ampere frame.
