What this MCCB brings to a motor branch
Rated 100 A continuously across the full ambient range from 40 °C to 70 °C — no derating curve to chase — and it delivers 187 kA interrupting capacity at 240 V, 121 kA at 415/440 V, and still holds 75.6 kA at 500 V.
The 86 mm depth fits standard MCCB panel footprints — no deep-can requirement — and the 105 mm width means it occupies three pole spaces on a DIN-rail or panel-mount backplate. Maximum power loss is 10 W, so heat dissipation inside a sealed enclosure is manageable — no forced cooling needed for a single unit, but stack several in a row and the cumulative loss matters.
Trip unit and release configuration
No trip indicator on the front face — the auxiliary switches (2 HQ) provide remote status instead. Short-time delay is adjustable from 4 s minimum to 17 s maximum, which gives selectivity coordination room downstream.
