Eaton CHQ220 - 20A, 2-Pole, Miniature Circuit Breaker (MCB)

Introducing the Eaton CHQ220 — a 20A, 2-Pole Miniature Circuit Breaker (MCB) designed to deliver dependable overcurrent protection in modern electrical distributions. Built for reliability, it integrates seamlessly into panelboards, switchboards, and control panels where safe, consistent performance matters.

The 2-pole configuration ensures both conductors trip together, providing safer fault isolation and minimizing arc energy during a fault. This coordinated protection helps protect downstream equipment, wiring, and operators, while simplifying diagnostics when trips occur.

• Current rating: 20A
• Poles: 2-Pole
• Breaker type: Miniature Circuit Breaker (MCB)

Key use cases — where the CHQ220 shines in real-world environments:

• Panelboards and switchboards in industrial facilities that require reliable branch protection for feeders and critical circuits.
• Control panels in automation and OEM equipment, ensuring rapid, safe isolation during faults or maintenance.
• Motor control centers and process lines where dependable tripping protects motors, drives, and wiring.
• Commercial HVAC and lighting feeders where compact protection helps optimize space without compromising safety.

Why this CHQ220 stands out:

• Part of Eaton’s CHQ family, delivering predictable trip characteristics and consistent performance across installations.
• Compact, modular design that fits into standard Eaton-compatible panels, supporting efficient upgrades and maintenance without redesigns.
• Trusted Eaton reliability for industrial, commercial, and OEM applications, reducing downtime and supporting safer electrical distribution.

Practical guidance for selection and installation:

• Use the CHQ220 for circuits that require a 20A rating with two-pole protection to ensure simultaneous disconnect of both conductors.
• Verify compatibility with your existing panel system and ensure the installation footprint aligns with your enclosure design.
• Consult the Eaton CHQ product data for installation tips, trip characteristics, and environmental considerations to confirm suitability for specific environments.
