Square D PowerPact HLL36070T H-Frame 3P 70A Field-Interch TM
150A Frame | 70A | 3P | 125kA@240V, 100kA@480V, 50kA@600V | Thermal-Magnetic (Field-Interchangeable)
Engineered for demanding electrical systems, the Square D PowerPact HLL36070T is a H-Frame 70A 3-pole molded case circuit breaker with very high interrupting capacity. Rated at 125kA@240V, 100kA@480V, 50kA@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. Configured for unit mount installation, the HLL36070T utilizes lug (unit mount) connections with AL150HD Lug terminations designed for reliable conductor termination. The unit accommodates 14-3/0 AWG Al/Cu conductors within compact overall dimensions of 5.90" H x 4.50" W x 3.63" D weighing ~7 lbs, optimizing installation density in electrical distribution equipment. Compliant with UL 489, CSA C22.2 No.5, and IEC/EN 60947-2 international standards, the HLL36070T carries multiple certifications for worldwide acceptance and specification. Ideal for commercial buildings, industrial facilities, data centers, healthcare facilities, and critical infrastructure power distribution requiring reliable 70A 3-pole overcurrent protection. As part of the proven PowerPact family, the HLL36070T delivers dependable protection backed by Schneider Electric's extensive global engineering heritage and comprehensive industry-leading technical support resources.
