Rated continuous current holds at 32 A from 40 °C up to 50 °C, then gently derates to 30 A at 70 °C — no surprises in a warm enclosure.
Breaking capacity — the real headroom
The interrupting ratings on this unit are what separate it from a standard distribution MCCB. At 240 V it clears 220 kA; at 415 V it's still 154 kA; at 440 V it's 121 kA. Those numbers drop sharply at 500 V and 690 V to 17 kA — still enough for most motor branch circuits, but if your system runs at 480/500 V three-phase, verify the available fault current against that 17 kA ceiling.
Auxiliary contacts and integration
That gives you one N/O + N/C for status feedback and a separate alarm contact that changes state only on a trip — useful for remote fault indication without wiring through the aux. The trip indicator on the front confirms a thermal or magnetic trip visually.
Mounts on a DIN rail or panel base — 76.2 mm wide (3 in), 130 mm tall, 70 mm deep. Max power dissipation is 10.6 W, so if you're packing several of these in a sealed enclosure, factor that into the thermal budget.
