Built for demanding industrial environments, the Square D HJL26150 delivers 150A of continuous current capacity. This 2-pole PowerPacT H-Frame breaker utilizes fixed thermal-magnetic trip technology for precise LI protection. Designed as a unit-mount device, it fits securely into switchboards, enclosures, and industrial control panels. With an interrupting capacity of 65 kAIC at 480VAC, it handles high-fault conditions effectively. It features a Visi-Trip indicator for fast troubleshooting.
