Square D PowerPact HGL36045T H-Frame 3P 45A Field-Interch TM
150A Frame | 45A | 3P | 65kA@240V, 35kA@480V, 18kA@600V | Thermal-Magnetic (Field-Interchangeable)
The Schneider Electric Square D PowerPact HGL36045T is a H-Frame molded case circuit breaker rated at 45 amperes for 3-pole applications in commercial and industrial power distribution systems. This premium breaker delivers high interrupting capacity rated at 65kA@240V, 35kA@480V, 18kA@600V, operating at 600V AC / 250V DC for reliable overcurrent protection in critical electrical infrastructure. Designed with field-interchangeable trip unit capability, this breaker allows on-site trip unit replacement without replacing the entire breaker frame, significantly reducing maintenance costs, inventory requirements, and system downtime. The TMD (Field-Interchangeable) trip unit provides reliable overcurrent protection with proven thermal overload and magnetic instantaneous response characteristics. The HGL36045T features unit mount configuration with lug (unit mount) connections and AL150HD Lug terminations for straightforward installation. Accepting 14-3/0 AWG Al/Cu conductors, this breaker measures 5.90" H x 4.50" W x 3.63" D and weighs ~7 lbs, providing a compact footprint for space-efficient installation in panelboards, switchboards, and motor control centers. UL 489 listed and CSA C22.2 No.5 certified, the HGL36045T meets IEC/EN 60947-2 international standards for global project specification and acceptance. Applications include feeder circuit protection, branch circuit protection, motor control center installations, panelboard and switchboard applications, and industrial power distribution systems requiring H-Frame frame-class protection capabilities. As part of the proven PowerPact family, the HGL36045T delivers dependable protection backed by Schneider Electric's extensive global engineering heritage and comprehensive industry-leading technical support resources.
