The 25 kA interrupting rating at 240 VAC means it can safely clear a fault up to that level without upstream devices needing to intervene — relevant for high-fault-capacity industrial panels where selectivity with a downstream feeder breaker is required. Trip Curve K is a specialty magnetic-only characteristic (typically 8–12x In) designed for inductive loads like motor circuits and transformer primaries where a standard B or C curve would nuisance-trip on inrush. The 2-pole configuration covers a single-phase or two-leg circuit; the S800 family uses a modular DIN-rail footprint that matches standard enclosure rail. ## Sourcing and lifecycle The S802U-K25 carries a current lifecycle status per the manufacturer. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.","metaTitle":"ABB S802U-K25 MCB S800 2P K 25A, 25 kA","metaDescription":"ABB S802U-K25 MCB, S800 series, 2-pole, 25 A, Trip Curve K, 240 VAC, 25 kA interrupting rating.
