Square D | QOU220VH | Circuit Breaker | 20A | 2-Pole | 220V

The Square D QOU220VH Circuit Breaker is a precise, purpose-built protection device for 220V circuits that demand dependable 20A, two-pole performance. Designed for maintenance, retrofit, and replacement projects, this breaker slots into compatible Square D panels with confidence, preserving electrical safety and circuit integrity.

Key specifications at a glance

• Amperage: 20A
• Poles: 2-Pole
• Voltage: 220V
• Part number: QOU220VH (the best reference for compatibility)

Why this specific part matters

• Exact form factor and electrical ratings for Square D panel systems that accept QOU-series breakers, reducing guesswork during replacements.
• The 2-pole design provides simultaneous protection for both legs of a 220V circuit, helping prevent unbalanced loads and shared-neutral issues.
• Matching the part number is the most reliable way to ensure compatibility, avoiding mismatches that can jeopardize safety and code compliance.
• Ideal for retrofit and maintenance where replacing an aging breaker with a like-for-like unit keeps panels up to date without redesigning the protection scheme.

Use cases and ideal applications

• Residential or light commercial 220V circuits that require 20A protection — think large appliances, water heaters, and HVAC equipment in areas where a 240V supply is standard.
• Retrofits in existing Square D panels that explicitly specify QOU-series breakers for continued reliability and consistent trip characteristics.
• New installations in layouts that must match a strict 20A/220V protection profile for safety and code alignment.

Practical installation notes

• Before ordering, confirm fit and ratings against your panel’s labeling and the equipment you’re protecting. Use the QOU220VH part number as your primary compatibility reference.
• Follow standard safety practices: de-energize the panel, use proper tools, and torque connections per manufacturer guidelines to ensure a secure, low-resistance connection.
• When replacing, ensure the circuit’s load is within the breaker’s 20A rating and that the overall panel design accommodates an additional 2-pole device of this size.

Why choose this over generic equivalents

• Designed specifically for Square D panels with QOU-series compatibility, which minimizes guesswork and reduces the risk of non-conforming installations.
• Exact 20A, 2-pole, 220V specifications offer precise protection for dual-leg circuits, aligning with typical 240V-class systems without oversizing or underprotecting the circuit.
