Square D | LIP36300 | Circuit Breaker | 300A | 3-Pole | 600V

Meet the Square D LIP36300 circuit breaker—a robust, high-capacity protective device engineered for demanding three‑phase electrical systems. With a 300 A rating across 3 poles and a 600 V maximum voltage, this breaker delivers reliable overcurrent protection for heavy loads in industrial and commercial environments. It’s built for maintenance, retrofit, and replacement projects where exact specifications matter, making the LIP36300 a trusted choice for keeping critical equipment safe and online.

Key specifications

• Amperage: 300 A
• Poles: 3‑Pole
• Voltage rating: 600 V
• Reference: Part number LIP36300 (best compatibility reference)

Why this matters for your system

Choosing the right circuit breaker isn’t just about matching numbers—it’s about ensuring reliable protection for three‑phase circuits in demanding environments. The 300 A rating supports heavy feeders and motors, while the 3‑pole configuration protects all phases of a 3‑phase circuit. The 600 V rating sets a clear boundary for safe operation in higher‑voltage panels and equipment, helping minimize nuisance trips and downtime in industrial processes.

Compatibility & installation notes

• Verification is essential: Before ordering, confirm fit and ratings to ensure seamless integration with your existing panel or gear.
• Best reference for compatibility: Use the part number LIP36300 as your primary guide when matching parts and documentation.

Ideal applications and use cases

Designed for scenarios where robust three‑phase protection is required, the LIP36300 is well suited for:

• Industrial panels and switchgear in manufacturing facilities
• Retrofits or upgrades to handle higher loads on 3‑phase systems
• Replacement parts for older Square D installations that require exact specifications
• Commercial environments with heavy equipment and motor loads operating at up to 600 V

Practical considerations

If you’re upgrading or renewing protection in a 3‑phase 600 V circuit, this 300 A, 3‑pole unit provides a direct, specification‑matched option that aligns with Square D panel configurations. Keep the focus on compatibility with your existing gear, and rely on the LIP36300 part reference to streamline ordering and reduces the risk of mismatched components.
