ABB S203-C50 is a 3-pole molded case circuit breaker from the S 200 Series, designed to provide overcurrent protection through thermal-magnetic tripping with long time and instantaneous trip functions. It is rated for 50A at 480V AC, with a 6kA interrupting capacity at 480V, and supports 3-phase operation via a feed-thru connection. The unit measures 69 mm in depth, 88 mm in height, and 52.5 mm in width, weighing 2.87 lb, and accepts wire sizes from AWG 18 to AWG 8 (or AWG 18 to AWG 4 depending on configuration). It is certified to EN, IEC, and UL standards, with an operating temperature range of -13°F to 158°F (-25°C to 70°C). This breaker is suited for industrial applications requiring reliable branch circuit protection in panelboards or distribution systems.
