Square D KA26150AB – 150A 2 Pole Molded Case Circuit Breaker Last Chance

Built for heavy-duty applications, the Square D KA26150AB is a 2-pole, 150A molded case circuit breaker. It utilizes thermal-magnetic trip technology to deliver reliable long-time and instantaneous (LI) protection. This K-frame breaker mounts into Square D I-Line panelboards, featuring a factory-configured A-B phase connection. For modern upgrades, this legacy model is replaced by the PowerPact J-frame (JGA261501). With a 25kAIC rating at 480VAC, it includes a Visi-Trip indicator.
