Square D | LCP36300 | Circuit Breaker | 300A | 3-Pole | 600V | Bolt-On

Power distribution reliability starts with the right protective device. The Square D LCP36300 Circuit Breaker delivers dependable, like-for-like protection for demanding 3-phase systems with up to 600V and 300A, designed for bolt-on installation in compatible panels. Built to support maintenance, retrofit, and replacement projects, this unit ensures you can upgrade or refresh your panel without compromising safety or performance.

Key specifications

• Amperage: 300 A
• Poles: 3-Pole
• Voltage: 600 V
• Mounting: Bolt-On
• Part number: LCP36300

Why this model stands out

When your project requires a precise match to existing gear, the LCP36300 from Square D offers a straightforward, like-for-like replacement path. The bolt-on design provides a secure mechanical interface and robust contact reliability—key for minimizing downtime during maintenance or upgrades. With its 3-pole configuration, it protects three conductors in a single device, making it ideal for standard three-phase distribution setups in industrial and commercial environments.

Ideal use cases

• Maintenance on aging panels that previously used a 300A, 3-pole, 600V bolt-on breaker
• Retrofits where upgrading to higher efficiency or updated safety features is planned, but exact specs must be preserved
• Replacement of failed breakers in systems that rely on three-phase protection at 600V

Compatibility and buying guidance

For a successful fit, rely on the part number as your primary reference. Important: confirm fit and ratings against your panel’s datasheet or the enclosure manufacturer’s recommendations before ordering. The LCP36300 part number is the best reference to ensure you’re selecting the exact Square D model required for your system.

Practical considerations and tips

• Verify that your panel accepts bolt-on breakers and supports a 3-pole, 600V configuration before purchasing.
• Prepare for installation by following your facility’s electrical safety protocols and local codes to minimize downtime and ensure a safe replacement.
• Use this model when a like-for-like swap is needed to preserve protective characteristics and panel coordination without altering downstream protection settings.
