Square D | JGA36150 | Circuit Breaker | 150A | 18kA

Square D JGA36150 circuit breaker — a robust 150-amp device with an 18kA interrupting capacity, designed to deliver dependable protection in compatible Square D panelboards.

Built for maintenance, retrofit, and replacement projects where exact specifications matter, this breaker integrates smoothly with your existing Square D installations, helping you restore safe, reliable operation without unnecessary panel changes.

• Part number: JGA36150 — the most reliable reference for compatibility with Square D panels.
• Amperage: 150 A
• Interrupting rating: 18 kA
• Applications: ideal for maintenance, retrofit, and replacement in Square D panelboards and distribution panels
• Fit verification: confirm the breaker’s fit and ratings before ordering to ensure proper protection and panel compatibility

Why this Square D breaker stands out: it leverages Square D engineering for consistent tripping performance and a straightforward replacement path when restoring critical circuits. The 150A rating supports substantial load profiles in commercial or light industrial settings, while the 18kA interrupting capacity provides a safety margin against high fault currents, helping protect downstream devices and wiring.

Practical use cases:

• Retrofits in existing Square D distributions when an older or damaged breaker needs a direct, compatible match
• Routine maintenance cycles to refresh protective equipment and maintain compliance
• Load-up upgrades in service panels that require a 150 A rating without altering panel architecture

Note: To ensure proper operation and safety, always verify fit and ratings against your panel’s model and current specifications. The part number JGA36150 is the best reference for compatibility, so keep it handy when shopping or consulting documentation.
