Zinsco | QFP2150 | Circuit Breaker | 2-Pole | 240V

Meet the Zinsco QFP2150, a 2-Pole, 240V circuit breaker designed for maintenance, retrofit, and replacement projects where exact specifications matter. This isn’t a generic component—it’s a precise match for systems that require the QFP2150 part number to ensure proper fit and protection.

Key specifications

• Poles: 2-Pole
• Voltage rating: 240V
• Part number: QFP2150
• Brand: Zinsco

What problems this solves

When a 2-pole 240V circuit breaker in your panel trips frequently or fails to reset, the QFP2150 provides a precise, compatible replacement that aligns with the panel’s original design. It’s particularly suited for service upgrades, retrofits, or replacing a worn-out breaker while preserving electrical protection and panel integrity.

Why this breaker stands out

Compatibility is the core value here. The QFP2150 is identified by its part number, making it the most reliable reference for determining fit. This practicality is especially valuable for electricians and informed homeowners who understand the importance of matching mounting arrangements, terminal styles, and overall configuration with the panel.

Ideal use scenarios

• Retrofit projects in older Zinsco panels requiring a 2-Pole, 240V protective device
• Maintenance replacements where the existing unit is worn, damaged, or unavailable
• Electrical system upgrades that necessitate a standardized 240V two-pole protection scheme

Installation and safety notes

Always confirm panel model compatibility and verify ratings before ordering. Follow local electrical codes and safety practices during installation. If you’re unsure about fit or mounting, consult a licensed electrician to ensure proper compatibility and secure installation.
