Breaking capacity is substantial: 187 kA at 240 V, tapering to 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V — so at typical 400 V industrial supply, you're looking at over 100 kA fault-clearing capability, which covers high-fault panels without needing a current-limiting upstream device.
At 55 °C it drops to 156 A, at 60 °C to 151 A, at 65 °C to 147 A, and at 70 °C to 142 A. That's a gentle slope: you lose about 11% at the top of the operating range, which is better than many MCCBs that start derating at 40 °C. Maximum power loss is 33 W at rated load, so heat dissipation inside the enclosure is manageable — no forced cooling required for a single unit in a standard IP54 panel.
Footprint is 105 mm wide × 158 mm tall × 70 mm deep — that's a compact 3-pole MCCB for 160 A.
