• Poles: 3-Pole
• Voltage: 240V
• Part number: Q243015
• Compatibility note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.

Why this exact part matters

When your panel requires a specific 3-pole, 240V protection device, using the precise part number Q243015 eliminates guesswork and reduces the risk of mismatched components. This is especially important in retrofit and replacement scenarios where maintaining correct amperage, pole count, and voltage is critical to safe, dependable operation.

Ideal use cases

• Maintenance: keep spares on hand for scheduled service and quick swaps to minimize downtime.
• Retrofit projects: replace aging breakers with a model that aligns exactly with the panel’s 15A, 3-Pole 240V requirements.
• Replacement needs: restore proper protection in existing installations where the Q243015 specification is required.

How it performs in real-world scenarios

In its intended role, the Zinsco Q243015 delivers dependable circuit protection across 240V circuits that demand three simultaneous disconnects. This helps ensure that multiple hot conductors in a single panel are shut off together, supporting coordinated protection in multi-wire or 3-phase configurations where applicable. The result is predictable trips, safer maintenance work, and consistent protection aligned with your system’s design.

Compatibility and installation tips

• Always verify the panel label or manufacturer documentation to confirm that a 15A, 3-Pole, 240V breaker is the correct specification.
• Use the exact part number (Q243015) as the primary reference when checking compatibility.
• Power down the system and follow proper safety procedures before replacement or installation.
• If there’s any uncertainty about fit or ratings, consult a licensed electrician to prevent misapplication.

Keep the Zinsco Q243015 on hand for reliable, spec-matched protection that aligns with your 240V circuits. Clear compatibility references, concrete use cases, and a focus on exact specifications help you avoid unnecessary downtime and protect your electrical system with confidence.
