The JLA36150 Square D 3-Pole Circuit Breaker is a reliable protection solution with a 150A rating, operating at 600V. Designed for high-demand environments, it offers a robust 50KA interrupting capacity, ensuring efficient operation and safety. Ideal for commercial or industrial applications, it combines durability with superior performance. Perfect for your electrical needs.
The JLA36150 uses Square D's I-Line plug-in bus connection system, which allows the breaker to be installed or replaced without disturbing adjacent breakers or bus connections — a key advantage in industrial and commercial panelboards. Standard bolt-on breakers use a different mechanical and electrical bus interface and are not interchangeable with I-Line equipment.
Square D's J-Frame I-Line breakers can become difficult to find as product lines evolve. Northern Breaker Group specializes in obsolete and hard-to-find circuit breakers across Canada. Whether the JLA36150 is a current or discontinued part, we can help source it — contact our Calgary, Edmonton, or Vancouver counter for availability and lead time.
Yes. A 600V-rated breaker like the JLA36150 can be applied on lower-voltage systems such as 208V, 240V, or 480V, as it is rated for use up to 600V AC. Always verify the breaker's full ratings and confirm suitability with your electrical engineer or authority having jurisdiction (AHJ) for your specific installation.
