What this 320 A MCCB brings to the panel
The TM220 thermal-magnetic release gives you fixed short-circuit pickup at 3200 A (10× Ir), so it's set for motor or distribution duty right out of the box without dial-twiddling. This is a line-protection version, not a motor-protection variant with adjustable thermal curves. The 320 A rating holds flat from 40 °C to 50 °C, then derates to 292 A at 70 °C — so in a hot enclosure you lose about 9% of headroom. Front IP40 means it's splash-safe from the front but not sealed; mount it inside a cabinet, not outdoors.
Fit and integration notes
That's a standard MCCB footprint — it bolts into a panel busbar system or mounts on a backplate with the supplied hardware. No communication module onboard — this is a standalone breaker, not a smart metering device.
