Why this model matters
- Part number QJA221504 is the clearest reference for compatibility—use it to verify fit with your Square D panel and system requirements.
- Designed to withstand fault conditions up to 100kA at 240V, helping protect wiring, feeders, and downstream devices from overcurrent events.
- Specifically suited for retrofit and replacement projects where the exact QJA-series form factor and trip characteristics are required.
Ideal use cases
- Replacing a failed or outdated breaker in commercial or light-industrial panels that call for a 150A, 2-pole, 240V protection device.
- Retrofits that upgrade safety margins for high-load circuits feeding motors, reactors, or large distribution feeders.
- Maintenance inventories where having the exact matching part number minimizes downtime and misfits.
What sets it apart
- Exact alignment with Square D panel systems that require QJA-type breakers, ensuring proper mounting, trip curves, and electrical clearance.
- Clear, supplier-referenced specifications (150A, 2-Pole, 240V, 100kA) that translate into predictable protection performance and easier planning for replacements.
Practical notes for installation
- Always confirm fit and ratings before ordering to ensure compatibility with your panel model and application.
- Follow standard electrical safety practices: power down, verify labeling, and install in accordance with local codes and panel instructions.
- Keep the QJA221504 as a reliable, on-hand replacement part in environments where high-current protection is essential.
