Square D HDL36070 Three Phase Circuit Breaker

The HDL36070 is a 70 A, three‑pole PowerPacT H molded‑case circuit breaker designed for 600 V three‑phase systems, delivering up to 14 kA interrupting capacity at 600 V. Built by Square D (Schneider Electric) as part of the PowerPacT H family, this 3P unit uses thermal‑magnetic trip protection and is UL listed for industrial use. It features line‑side and load‑side lug terminals andaccepts conductors sized for 14‑3/0 AWG aluminum or copper, enabling straightforward panel wiring. This model is intended to protect feeders and three‑phase motors in commercial and light industrial power distribution, and its 600 V rating makes it suitable for higher‑voltage applications found in demanding environments. The HDL36070 can be configured for reverse‑fed applications in appropriate panels, and it is a widely cataloged Square D device referenced by distributors as a 70 A, 3P, 600 VAC protection solution.
