Square D | LHL36150V | Circuit Breaker | 150A | 3-Pole | 36150V

Meet the Square D LHL36150V circuit breaker, a purpose-built solution for three-phase protection that aligns with maintenance, retrofit, and replacement projects. This 3-pole unit delivers reliable overcurrent protection when you need to restore safe, continuous operation in your electrical system, using a reference part number that’s designed to match your existing installation exactly.

Key specs at a glance

• Amperage: 150A
• Poles: 3-Pole
• Voltage: 36150V
• Part number reference: LHL36150V (best compatibility reference)

Why choose the LHL36150V for your project

This breaker is purpose-made for Square D panels and systems that require a precise, exact-match replacement. By using the LHL36150V, you ensure your panel continues to meet its original protection characteristics, reducing the risk of improper fit or mismatched trip performance. The part-number-based compatibility approach is your best safeguard when retrofitting legacy equipment or upgrading components in an existing distribution setup.

Ideal use scenarios

• Maintenance outages where a direct, authentic replacement is needed to minimize downtime
• Retrofit projects that bring aging three-phase systems up to current protection standards
• Replacement in commercial or industrial panels that require a 150A, 3-pole configuration

Installation and compatibility tips

Before ordering, confirm fit and ratings against your panel documentation. The LHL36150V should be used when the panel or enclosure specifies this part number as the compatible reference. Because panel labeling and catalog references can vary, relying on the exact part number is your best path to a smooth retrofit with predictable protection characteristics.

For best results, store and handle with standard electrical safety practices, and ensure the surrounding system (bus bars, mounting provisions, and conductors) aligns with the 3-pole, 150A, 36150V rating. This approach helps preserve system integrity, reduces rework, and keeps downtime to a minimum during replacement or upgrade projects.
