Square D KC341251021 is a molded case circuit breaker designed for providing reliable overcurrent protection in three-phase industrial power distribution systems. It features a 125A current rating and a 480V AC voltage rating, housed within a compact K-Frame thermal-magnetic unit that provides both long-time and instantaneous (LI) trip functions for coordinated protection. This three-pole breaker utilizes a plug-in I-Line style connection for simplified installation and maintenance, supports wire sizes from AWG 14 to 3/0 for aluminum or copper conductors, and is UL and CSA certified for safety compliance. Its 65kA interrupting rating at 480V AC and included 120V AC shunt trip mechanism make it suitable for controlling and protecting feeder circuits in commercial and industrial panelboards.
