Schneider Electric HDA36150U33X Circuit Breaker

Schneider Electric's Square D PowerPact HDA36150U33X is a 150-amp, three-pole molded-case circuit breaker designed for 600-volt AC systems, built for I-Line plug-in installation in industrial distribution panels. As part of the PowerPact H family, it provides overcurrent protection for three-phase feeders and branch circuits, compatible with Square D PowerPact H equipment and I-Line bus configurations. The HDA36150U33X model is intended for use in commercial and industrial electrical distributions that require compact, reliable protection with predictable trip characteristics. Key specifications include a 150 A rating, 3 poles, and a 600 VAC rating, with molded-case construction suited to panelboards and switchgear environments. The I-Line design supports secure, straightforward integration with Schneider Electric’s bus systems and promotes a compact footprint in dense electrical layouts. Typical applications include motor control centers, distribution panels, and other industrial power-distribution setups where safe interruption of fault currents is essential and compatibility with Square D enclosure ecosystems is desired.
