The LH36250 Square D 3P 250A 600V I-Line Circuit Breaker is engineered for reliable performance in high-demand applications. With a 25KA interrupting capacity, it ensures robust protection against overloads and short circuits. This durable, three-phase breaker is ideal for commercial and industrial environments. Upgrade your electrical system with confidence.
The LH36250 uses Square D's I-Line plug-in connection, so it is designed for Square D I-Line panelboards and switchboards rated at 600 V. It is not compatible with QO loadcentres or Homeline panels. If you're unsure whether your enclosure accepts I-Line breakers, send us the panel model number and our team will confirm compatibility.
Availability of specific Square D LH-frame breakers can vary. Northern Breaker Group specialises in obsolete and hard-to-find breakers, so even if the LH36250 has been superseded or is difficult to source through standard channels, we can often locate new, reconditioned, or equivalent stock. Contact any of our Calgary, Edmonton, or Vancouver counters for a quote.
The LH36250 is rated 250 A, 600 V, 25 kA and is suitable for use as a branch or feeder breaker in I-Line switchboards and panelboards. Whether it can serve as a main breaker depends on the specific panel design, bus rating, and your local electrical code requirements (Canadian Electrical Code, Part I). We recommend consulting your panel documentation and a licensed electrician to confirm the application before installation.
