Square D HJL36070 - 70 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Square D HJL36070 is a 70A, 600V, 3-pole molded case circuit breaker designed to deliver dependable branch circuit protection for panelboards and loadcenters. Its compact, space-saving form factor makes it ideal for tighter electrical spaces, while the thermal-magnetic trip unit provides stable, repeatable protection as loads vary throughout the day.

• Space-efficient design — the compact molded case footprint helps maximize panel capacity without sacrificing protection.
• Reliable protection — a thermal-magnetic trip unit responds quickly to overcurrent and short-circuit conditions, ensuring consistent performance across operating conditions.
• Three-pole configuration — ideal for three-phase systems and multi-pole protection in single or multi-circuit panel layouts.
• OEM compatibility — specifically engineered to pair with matching OEM loadcenters and panelboards for streamlined replacement and installation.
• Broad suitability — suitable for residential, commercial, and light industrial electrical systems, handling diverse protection needs from lighting to equipment feeds.

Use cases and practical scenarios where the HJL36070 shines:

• Protecting branch circuits in compact residential or light commercial panelboards where space is a premium.
• Providing dependable short-circuit protection for HVAC, pumps, lighting, and outlet feeders in commercial environments.
• Serving as a ready-to-install replacement in compatible Square D panelboards to maintain system protection without reengineering the panel.

Why choose this breaker over alternatives? The HJL36070 combines a rugged molded case with a precise thermal-magnetic trip mechanism, translates to predictable trip behavior under varying loads, and removes the guesswork from protection settings. Its 3-pole design ensures complete protection of multi-wire branch circuits, reducing the risk of nuisance trips and electrical faults in complex panel configurations.
