LAL36350 SQUARE D 3P 350A 600V 22KA

The Square D LAL frame is a heavy-duty molded-case circuit breaker frame rated for 600V and higher ampere ratings, designed for commercial and industrial distribution. It differs from smaller frames (such as the QO or Homeline series used in residential loadcentres) by offering higher interrupt ratings, larger conductor terminations, and compatibility with industrial panelboards and switchboards rather than residential panels.

The LAL series has been superseded in Square D's current lineup by newer MCCB frames. However, Northern Breaker Group specializes in obsolete and hard-to-find breakers — we maintain extensive inventory and sourcing networks across Canada. Contact our Calgary, Edmonton, or Vancouver counters or submit a quote request and we'll locate the LAL36350 for you.

At 350A, the LAL36350 accommodates large-gauge copper or aluminum conductors appropriate for a 350A, 600V circuit — typically in the range of 350–600 kcmil, though the exact conductor range depends on the specific terminal lugs installed. Always verify torque specs and conductor compatibility against the breaker's nameplate and installation instructions, and ensure connections meet CEC requirements for your jurisdiction.
