What this 160 A MCCB brings to the panel
It's designed for line protection — think main feeder or large branch in a distribution panel. The interrupting ratings climb steeply at lower voltages: 220 kA at 240 V, 154 kA at 415 V, still 75.6 kA at 440 V, and holds 17 kA at 500 V and 690 V. That makes it a solid choice for high-fault-capacity mains where you need to clear a dead short without upstream coordination headaches.
Thermal derating — it's not 160 A everywhere
Above that it derates linearly: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. The 38 W max power loss means it dumps some heat into the enclosure; plan ventilation accordingly.
It's a panel-mount MCCB — no DIN rail, bolts directly to the backpan.
