ABB S3N-3P-200A-480V Molded Case Circuit Breaker

ABB S3N-3P-200A is a 3-pole Molded Case Circuit Breaker (MCCB) from ABB's SACE Isomax family, rated 200 A for three-phase systems up to 480 V AC (600 V maximum) and with a short-circuit interrupting capacity of 25 kA at 480 V (35 kA at 415 V). It employs a thermal-magnetic trip mechanism with separate long-time and instantaneous trip functions and uses a bolt-on mounting suitable for panel installations; the trip is non-interchangeable to maintain consistent protection characteristics across assemblies. This device is suitable for reverse-feed configurations in electrical distribution schemes, providing robust protection in industrial and commercial power circuits.
