The 50 kA interrupting capacity at both 480 VAC and 250 VDC means it can safely clear a fault up to that level without welding contacts or cascading upstream, which is critical for high-fault-capacity panels like those fed by a large transformer or generator. DIN-rail mounting means it snaps directly into a standard 35 mm rail inside the panel — no special adapter or bracket needed. The 16 A rating and 2-pole form factor cover single-phase or two-wire DC branch circuits in control panels, distribution boards, or sub-feed applications.","metaTitle":"S802S-UCB16 ABB High Performance MCB, 2P, 16A Curve B, 50 kA","metaDescription":"ABB S802S-UCB16 high performance miniature circuit breaker, 2-pole, 16 A, Trip Curve B, 480 VAC / 250 VDC, 50 kA interrupting capacity.

This suits resistive loads like heaters, lighting, and control transformers — not motor starts or high-inrush loads that need a C or D curve."},{"question":"Where can I buy S802S-UCB16?","answer":"The S802S-UCB16 is sourced to order against an RFQ through independent distribution.
