Square D | MEL36250LI | Circuit Breaker | 250A | 3-Pole | 600V | 65kA | Feed-Through

The Square D MEL36250LI is a purpose-built 250A, 3-pole circuit breaker with a 600V rating and a 65kA interrupting capacity, designed for feed-through applications. This device is ideal for maintenance, retrofit, and replacement projects where exact specifications matter and reliable interruption across all three phases is required.

Key specifications

• Amperage: 250A
• Poles: 3-Pole
• Voltage: 600V
• Interrupting rating: 65kA
• Type: Feed-Through
• Part number: MEL36250LI

What makes this MEL36250LI unique

Unlike standard feeders, the MEL36250LI leverages a feed-through design that facilitates downstream connections within a single, integrated unit. This can simplify wiring in multi-panel installations and support cleaner, more organized feeder layouts. With a robust 65kA interrupting capability, it provides reliable protection for demanding three-phase loads common in industrial and commercial applications, while the 600V rating covers a wide range of distribution environments.

Ideal use cases

• Maintenance work where an exact, compatible replacement is required in existing Square D panels.
• Retrofit projects aiming to upgrade or extend feeders to downstream panels without adding separate lugs or adapters.
• New installations in industrial facilities needing a high-current, three-phase protection solution with feed-through capability.

Compatibility and ordering guidance

For the best fit, verify compatibility by matching the exact part number MEL36250LI and ensuring the panel and downstream circuits align with the 250A, 3-pole, 600V, 65kA specifications. The part number is the most reliable reference for compatibility, so use it as the primary checklist item before ordering. As with all critical protection devices, confirm fit and ratings before proceeding with installation.

In short, the MEL36250LI delivers precise, high-capacity protection for complex, three-phase feeder configurations, making it a thoughtful choice for professionals tackling maintenance, retrofit, or replacement projects that demand dependable performance and straightforward downstream wiring.
