What this 160 A MCCB delivers in the panel
It's built for main feeder or large subfeed duty in distribution panels where you need a full 160 A frame — no derating down to a smaller continuous rating. The interrupting capacity sits at 220 kA at 240 V, 154 kA at 415 V, and still holds 17 kA at 690 V, so it handles high-fault scenarios without cascading upstream.
Above that, it derates: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Maximum power loss is 38 W. If you're packing this into a high-density enclosure, that thermal curve and loss figure tell you where the ventilation needs to be.
Dimensions are 101.6 mm wide, 130 mm tall, 70 mm deep — a 4-inch-wide footprint that matches the standard SENTRON 3VA frame.
