Square D | HJP36150 | Circuit Breaker | 150A | 3-Pole

The Square D HJP36150 circuit breaker is a rugged, three-pole protection device designed for 3‑phase electrical systems. With a 150A rating, this model is ideal for crews tackling maintenance, retrofit, or replacement projects where precise specs matter and reliable protection is non‑negotiable. Identified by part number HJP36150, it’s built to align with Square D’s engineering standards and panel configurations that require a 3‑pole, 150A solution.

Key features that matter in the field

• Amperage: 150 A — strong, consistent protection for demanding circuits.
• Poles: 3‑Pole — suited for 3‑phase installations and panel configurations that require three conductors and a common trip.
• Exact reference: Part number HJP36150 — using the exact number is the most reliable way to confirm compatibility.
• Versatile use: Designed for maintenance, retrofit, and replacement where matching specs are essential.

Why this model is the right choice for your project

Choosing a breaker by part number ensures a precise fit, reliable contact with the bus bars, and predictable electrical behavior across your Square D system. The HJP36150 designation signals compatibility for panels and assemblies that require a 150A, 3‑pole configuration, reducing guesswork during installation and minimizing downtime due to mismatches.

Ideal use cases and applications

• Upgrading or replacing aged or worn three‑pole breakers in commercial or industrial panels.
• Retrofit projects where a 3‑phase, 150A protection device is required to support upgraded loads.
• Maintenance scenarios that demand a direct, spec‑matched replacement to maintain system integrity.

Compatibility and installation notes

Notes to ensure the right fit: confirm fit and ratings before ordering, and rely on the part number HJP36150 as the best reference for compatibility. Before installation, verify that your panel model and labeling indicate support for a 150A, 3‑pole device of this type, and follow all applicable safety and local electrical codes during replacement or retrofit work.

With the Square D HJP36150, you’re choosing a purpose‑built, spec‑accurate circuit breaker that supports reliable protection in 3‑phase systems, helping you complete maintenance or upgrades with confidence and clarity.
