Asea Brown Boveri S202U-K25 Molded Case Circuit Breaker

ABB S202U-K25 is a two-pole molded-case circuit breaker from ABB’s System pro M compact S200U family, rated at 25 A with a Type K tripping characteristic. It is intended for DIN-rail mounting in low-voltage distribution panels and is UL 489 listed for use in the United States and Canada. This 2P device protects two conductors in 240 V-class circuits, making it suitable for panelboards and motor-control centers where reliable overcurrent protection on a compact form factor is required. The S202U-K25 variant is part of ABB’s compact protection lineup, designed to fit space-constrained electrical distribution installations while delivering ABB’s protection and trip reliability in a standard DIN-rail package. Typical applications include commercial wiring panels, small machinery feeders, and retrofits in existing enclosures where a 25 A, two-pole protection device is needed.
