It carries an ETU320 electronic trip unit with an adjustable trip range from 95 A up to 756 A, so you set the actual protection threshold to match the downstream load — not fixed at the 63 A frame rating.
This MCCB delivers 242 kA interrupting capacity at 240 V, dropping to 187 kA at 415 V and 440 V, then 121 kA at 500 V. At 690 V it still clears 3.7 kA.
Thermal performance — no derating up to 70 °C
That simplifies panel layout in warm environments or enclosures with multiple heat sources.
The 4-pole form factor takes up the same footprint as a standard 4-pole MCCB — no special cutout or adapter plate needed.
