Square D PowerPact HDL36125T H-Frame 3P 125A Field-Interch TM
150A Frame | 125A | 3P | 25kA@240V, 18kA@480V, 14kA@600V | Thermal-Magnetic (Field-Interchangeable)
Engineered for demanding electrical systems, the Square D PowerPact HDL36125T is a H-Frame 125A 3-pole molded case circuit breaker with standard interrupting capacity. Rated at 25kA@240V, 18kA@480V, 14kA@600V and operating at 600V AC / 250V DC, it provides reliable and consistent protection for power distribution infrastructure applications. 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. This unit mount breaker features lug (unit mount) connections with AL150HD Lug terminations, accepting 14-3/0 AWG Al/Cu conductors for versatile wiring applications. With overall dimensions of 5.90" H x 4.50" W x 3.63" D and weighing ~7 lbs, the HDL36125T delivers H-Frame frame protection in a space-efficient package suitable for dense electrical equipment layouts. UL 489 listed and CSA C22.2 No.5 certified, the HDL36125T 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 HDL36125T delivers dependable protection backed by Schneider Electric's extensive global engineering heritage and comprehensive industry-leading technical support resources.
