GE | A3020 | Circuit Breaker | 20A | 2-Pole | 240V

The GE A3020 circuit breaker is a precise, ready-to-install solution for keeping 240V circuits safely protected. Engineered as a 20-amp, 2-pole unit, it delivers reliable fault protection for panels that require this exact specification. Ideal for maintenance, retrofit, and replacement projects, this breaker helps restore critical 240V circuits with minimal downtime.

Key features at a glance

• Amperage: 20A
• Poles: 2-Pole
• Voltage rating: 240V
• Part number: A3020
• Best reference for compatibility: Use the A3020 part number to confirm fit with your panel.

Why choose the GE A3020 for your 240V applications?

When your service panel calls for a 20A, 2-pole 240V breaker, the GE A3020 offers a purpose-built, factory-made solution designed to align with GE’s engineering standards. The part number is the most reliable clue for compatibility, helping you avoid mismatched breakers that can compromise panel performance and safety. This unit is particularly suited for retrofit projects or replacements where maintaining the original electrical protection scheme is essential.

Use cases and practical applications

• Restoring protection to a 240V circuit feeding large appliances or equipment in residential or light commercial settings.
• Replacing a failing or obsolete 2-pole breaker in GE-approved panels that specify A3020 or equivalent specifications.
• Retrofits where panel labeling indicates a 20A, 2-pole, 240V breaker is required to maintain code-compliant circuit protection.

How this compares and what to watch for

This GE breaker is designed to be the right match when the panel or the replacement plan references A3020. Always confirm fit and ratings before ordering by cross-checking the part number against your panel’s documentation. While other breakers may offer similar amperage and voltage, using the exact A3020 specification helps ensure proper mechanical fit, electrical contact, and reliable protection without introducing compatibility issues.

Tips for a smooth, safe installation

• Turn off the main power and verify there’s no load on the circuit before replacing the breaker.
• Consult your panel’s labeling to ensure the A3020 is an approved type for that location.
• Handle the unit with clean hands and avoid touching the conductive terminals to minimize corrosion risks during installation.
• After installation, test the circuit with appropriate equipment to confirm proper tripping behavior and restoration of power when the fault is cleared.
