The SQDHCJ23736 is a Square D 600A I-Line HCJ Interior panel designed for superior performance and reliability. This robust electrical panel features a versatile design ideal for commercial and industrial applications, ensuring efficient power distribution. With its durable construction and optimal circuit management, it’s perfect for both new installations and upgrades.
The HCJ I-Line interior accepts Square D I-Line plug-on circuit breakers. I-Line breakers are a distinct Square D system — standard QO or Homeline breakers are not compatible. Contact our team if you need help identifying the correct I-Line breakers for your branch circuits.
The SQDHCJ23736 is an interior assembly only — it includes the 600A bus, neutral bar, and breaker mounting structure, but requires a compatible Square D HCJ Series panelboard enclosure (trim and box sold separately or as part of a complete assembly). If you're unsure which enclosure matches, reach out and we can help you spec the full package.
Yes — the HCJ I-Line interior is well-suited for both new installations and retrofits/upgrades in existing Square D commercial or industrial panelboards, provided the enclosure dimensions and bus configuration are compatible. Because interior-to-enclosure fit is cabinet-specific, we recommend sharing your existing panel details with our team before ordering to confirm compatibility.
