Square D HDL36090 Low Voltage Circuit Breaker

Square D PowerPact H HDL36090 is a 90 A, three-pole molded-case circuit breaker for 600 VAC three-phase systems, featuring line- and load-lug terminals and cable-in/cable-out termination for straightforward installation in industrial panels. It delivers thermal-magnetic overcurrent protection with an 80% continuous-load rating and a 14 kA short-circuit interrupting capacity at 600 VAC, making it suitable for feeders and motor circuits in industrial distribution. The HDL36090 is part of the PowerPact H family, designed for rugged industrial environments and compatible with standard PowerPact H trip characteristics across HDL models. This model is commonly specified for 3-phase protective applications in commercial and industrial power distribution where compact, reliable MCCB protection is required.
