This MCCB delivers 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The steep drop above 500 V is characteristic of a current-limiting design optimized for the 240–500 V range common in industrial distribution. For a 480 V panel, the 187 kA interrupting rating gives substantial headroom above typical available fault currents, so selectivity with downstream breakers is achievable without oversizing the upstream device.
Maximum power dissipation is 0.6 W, negligible for thermal budgeting inside a crowded panel.
