Ratings and what they mean for fit
The 3VA1132-4ED42-0AA0: The 32 A rating holds across 45 °C to 50 °C ambient; at 55 °C it derates to 31 A, and at 70 °C to 30 A. That means in a warm panel — say a 50 °C enclosure — you still get full 32 A continuous, but above that the thermal curve governs. The interrupting capacity drops with system voltage: 52.5 kA at 440 V, 11.9 kA at 500 V and 690 V. For a 480 V distribution board, the 11.9 kA figure is the one that determines SCCR compliance. The adjustable short-circuit release (li) maxes at 320 A, giving selectivity headroom downstream. The TM210 release is a fixed thermal-magnetic design — no electronic adjustment, no communication function. That keeps the part simple and reliable for standard line protection, but if you need ground-fault monitoring or N-conductor protection, this variant omits both. Insulation voltage is rated at 800 V, and the maximum DC operational voltage is 600 V, so it suits both AC and DC applications within those limits. The front face carries IP40 protection — fine for a closed panel, not for washdown environments.
Deployment context
This MCCB mounts on a DIN rail or directly to a panel backplate via the standard SENTRON footprint. The dimensions are 70 mm depth, 101.6 mm width, 130 mm height — fits the common 4-pole MCCB cutout. An optional motor drive (product extension available) allows remote tripping or reset in automated lines.
