Square D HDA36100 Molded Case Circuit Breaker

Square D PowerPact HDA36100 Molded Case Circuit Breaker is a 100 A, 3-pole protective device engineered for industrial and commercial power distribution, rated for 600 V AC and 50/60 Hz. It uses a thermal-magnetic trip mechanism and delivers 14 kAIC interrupting capacity at 600 V, allowing rapid isolation of faults while protecting wiring and equipment. Part of the PowerPact H family, the HDA36100 features I-Line termination and is compatible with Square D Homeline load centers, facilitating integration in existing Square D installations. Its long-time and instantaneous trip characteristics provide a balanced protection strategy across three-phase feeders, enabling coordination with upstream protection to minimize nuisance interruptions. With a rugged molded-case construction, this MCCB is designed for installation in distribution panels, control panels, and other three-phase electrical systems in commercial and light-industrial environments. Applications include feeder protection for motors, pumps, and process equipment where reliable overload and short-circuit protection at 600 V is required.
