Breaking capacity — the real-world interrupt rating
This MCCB carries a 187 kA interrupting capacity at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V.
Current derating in a warm panel
Above that it starts to step down: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, 36 A at 70 °C.
Dimensions: 130 mm height, 76.2 mm width (3-pole), 70 mm depth. Comes with 2 auxiliary switches (HQ type) pre-installed, so you've got status feedback to the PLC without adding a separate aux block.
What it does not have
It's a bare-bones line-protection MCCB — thermal-magnetic only. If your spec calls for electronic trip adjustment or remote tripping, this isn't the variant.
