Square D | A1L330 | Circuit Breaker | 30A | 3-Pole | 240V | 10kA | Feed-Through

Introducing the Square D A1L330 Circuit Breaker — a dedicated 30A, 3-pole, 240V protection device with a feed-through design that combines robust electrical protection with streamlined downstream power distribution. Boasting a 10kA interrupting rating, it’s engineered to handle demanding loads while keeping panel layouts efficient in commercial and industrial settings.

What sets the A1L330 apart is the feed-through capability, enabling power to be distributed downstream from the same device. This makes it a smart choice for maintenance, retrofit projects, or replacements where you need to preserve existing wiring while upgrading protection and circuit organization. It’s a precise fit for Square D panels that require a 3-pole, 240V feed-through solution.

Key specifications

• Amperage: 30A
• Poles: 3-Pole
• Voltage: 240V
• Interrupting rating: 10kA
• Configuration: Feed-Through
• Part number: A1L330

Ideal use cases

• Maintenance or retrofit projects in 3-phase 240V panels that require downstream distribution from the breaker
• Replacement part for compatible Square D installations, ensuring panel continuity and protection
• Downstream feeding in configurations where a single, organized distribution point is preferred

Compatibility and installation tips

• Confirm fit and ratings before ordering: Match the panel model, bus arrangement, and rating to avoid compatibility issues.
• Reference the part number: Using A1L330 as the compatibility reference helps ensure correct replacement and electrical performance.
• Safety first: De-energize equipment and follow proper lockout/tagout procedures during installation or replacement.
• Check documentation: Verify with your panel’s catalog or manufacturer manual to ensure the 3-pole 240V feed-through configuration aligns with your system.
