Square D | LHF36350V | Circuit Breaker | 350A | 3-Pole | 36350V

Introducing the Square D LHF36350V Circuit Breaker—a robust, high-current, three-pole protective device designed to safeguard demanding electrical systems. Built to integrate seamlessly with Square D panels, this model is the go-to choice for maintenance, retrofit, and replacement projects where exact spec matching matters.

• Amperage: 350 A for reliable protection of large feeders and busways.
• Poles: 3-Pole configuration ensures balanced trip across all three phases.
• Voltage rating: 36350 V, enabling use in higher-voltage commercial/industrial environments.
• Part reference: LHF36350V—the most precise reference to guarantee compatibility with the corresponding Square D equipment.
• Compatibility note: Confirm fit and ratings before ordering; the part number is your best reference for cross-referencing panels, buses, and mounting style.

Use cases and benefits:

• Best suited for upgrades or replacements in existing Square D installations where a 350 A, 3-phase protection device is required.
• Ideal for facilities undergoing capacity upgrades, panel retrofits, or reconfigurations that demand high-current circuit protection without changing downstream wiring.
• Designed to minimize downtime by providing a straightforward, component-level replacement that matches the original LHF-series footprint and termination style.

Why choose this specific model? Its 350 A rating paired with a 3-Pole design delivers coordinated protection for 3-phase systems, reducing the risk of unbalanced faults and helping protect motors, transformers, and feeders from overcurrent events. By sticking with the Square D LHF family, you preserve compatibility with existing breakers, panels, and accessories—a practical choice for facilities aiming to maintain consistent protection standards across plant floor electricals.

In short, the Square D LHF36350V Circuit Breaker is a purpose-built solution for high-current 3-phase protection where exact spec fidelity and reliable replacement are critical.
