Panel & Switchboard Compatibility

The Square D HJL36050 is a 3-pole, 50A, 600V, 25kA I-Line moulded-case circuit breaker in the HJL frame. As an I-Line plug-in device, it is designed to mount in Square D I-Line panelboards and switchboards — commercial and industrial enclosures that accept the I-Line bus system — not in QO or Homeline residential loadcentres. It is suited for branch-circuit and feeder protection in industrial facilities, commercial buildings, and manufacturing environments operating at up to 600V AC.

  • Frame: HJL (I-Line plug-in)
  • Poles / Amperage / Voltage: 3P / 50A / 600V AC
  • Short-Circuit Rating: 25kA

Send us your panelboard or switchboard model and we'll confirm fit before you order.

No — the HJL36050 uses Square D's I-Line plug-in bus system, which requires an I-Line compatible panelboard or switchboard. It cannot be installed in standard QO or Homeline residential loadcentres, nor in bolt-on style panelboards. If you're unsure whether your enclosure accepts I-Line breakers, send us the panel model number and we'll verify compatibility.

Sourcing obsolete and hard-to-find breakers is our specialty. Whether the HJL36050 is a current catalogue item or has been discontinued, our Calgary, Edmonton, and Vancouver teams maintain extensive inventory and supplier networks across Canada. Contact us for a quote and lead-time confirmation.

Some Square D HJL-frame breakers support interchangeable trip units, allowing the ampere rating to be adjusted without replacing the entire breaker body — which can reduce downtime and cost. However, not all configurations are field-interchangeable. Please confirm your specific requirements with our team so we can advise on the correct trip unit or replacement breaker for your application.
