Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that place it in the high-fault-current class for industrial distribution.
What the interrupting ratings mean for panel coordination
That number governs selectivity with upstream devices: a 220 kA-rated MCCB at the service entrance lets you coordinate downstream branch breakers with lower interrupting ratings, avoiding a cascade trip. At 415 V the 154 kA still covers most transformer secondary faults; at 690 V the 17 kA is adequate for motor-circuit protection but not for high-fault utility ties.
Derating and ambient temperature profile
Above that it derates linearly: 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, and 14.4 A at 70 °C.
The 3-pole footprint matches the standard SENTRON 3VA panel cutout. Front IP40 protection is sufficient for enclosed distribution boards but not for washdown environments. The undervoltage release (UVR) is wired separately — verify control voltage matches the coil rating before energizing.
