The Q232150H Square D 3P 150A 240V I-Line Breaker is a durable and reliable circuit breaker designed for efficient performance in high-demand applications. This three-pole breaker offers robust protection against overloads and short circuits, ensuring safety and reliability for your electrical systems. Perfect for residential and commercial installations alike.
The Q232150H uses Square D's I-Line plug-in mounting system, making it compatible with Square D I-Line panelboards and switchboards designed to accept I-Line plug-in breakers. It is not interchangeable with QO or Homeline residential loadcentres. Contact us with your panelboard model number and we'll verify compatibility.
The 'H' suffix on Square D Q2-frame breakers designates a higher interrupting rating — in this case 22kAIC at 240V — compared to the standard interrupting rating of the base Q2 series. Always confirm your system's available fault current to ensure the breaker's interrupting rating meets or exceeds it.
Square D's I-Line Q2-frame breakers have seen product-line updates over the years. Northern Breaker Group specializes in obsolete and hard-to-find breakers across Canada, so whether the Q232150H is a current or legacy part, we can source new, reconditioned, or equivalent stock. Reach out to our Calgary, Edmonton, or Vancouver counters for availability and a quote.
