Square D | LHB36200 | Circuit Breaker | 200A | 3-Pole | 600V

Square D LHB36200 Circuit Breaker is a robust, high-current protective device engineered for demanding three-phase electrical systems. At 200A with a 3-pole design and a 600V rating, it’s built to safeguard heavy feeders and critical equipment in commercial and industrial environments alike. This breaker excels in maintenance, retrofit, and replacement projects where exact specs and reliable performance matter.

• 200A protection for major feeders and three-phase circuits, helping prevent damage from overloads and short circuits.
• 3-Pole configuration provides synchronized interruption of all three phases, improving fault isolation and system stability.
• 600V maximum operating voltage suited for higher-voltage distribution within commercial and industrial facilities.
• Compatibility-focused reference This unit’s part number, LHB36200, is the best reference for matching replacement or retrofit needs—always confirm fit and ratings on the panel label before ordering.
• Versatile for maintenance, retrofit, and replacement Ideal when upgrading aging protection, integrating into new expansions, or replacing existing Square D devices with a like-for-like specification.

Who benefits most from the LHB36200? electrical contractors performing panel retrofits, facility engineers upgrading service feeders, and maintenance teams tasked with reliable, long-term protection in three-phase systems. It’s particularly well-suited for service panels, industrial control panels, and large commercial distributions that require consistent, predictable trip performance and easy field replacement within a Square D ecosystem.

Practical considerations to ensure a smooth match: always verify the breaker’s fit and ratings against the panel’s labeling, use the LHB36200 as your primary compatibility reference, and plan for proper panel labeling and documentation after installation. When you’re upgrading to a high-current, three-pole solution, this Square D circuit breaker delivers dependable protection without compromising panel layout or future serviceability.
