Its 50 kA interrupting rating at 480 VAC and 250 VDC gives it a high fault-clearing capacity for industrial panel feeders where available short-circuit current is substantial — the 50 kA figure is the same on both AC and DC sides, so it handles DC bus faults without derating the interrupt rating. Mounts on a DIN rail in the standard enclosure footprint, which keeps panel layout consistent with other modular devices in the same distribution board.","metaTitle":"S802S-UCB63 63A 2P Trip Curve B DIN Rail MCB, 480VAC/250VDC","metaDescription":"S802S-UCB63 high-performance MCB, 63A, 2-pole, Trip Curve B, 50kA interrupting rating at 480VAC/250VDC.
