Square D | JJA36225SA | Circuit Breaker | 225A | 600V | 25kA

Engineered for the demanding reliability that industrial power systems require, the Square D JJA36225SA circuit breaker delivers precise overcurrent protection for 225A circuits operating up to 600V. With a robust 25kA interrupting rating, it’s built to handle fault currents cleanly, helping minimize downtime and protecting motors, feeders, and distribution panels from damage.

This unit is purpose-built for maintenance, retrofit, and replacement projects where exact specifications matter. The JJA36225SA is your clear choice when upgrading or renewing a panel that expects a JJA-series Square D breaker. The part number is your best reference for compatibility, ensuring a secure fit and reliable performance in your existing Square D infrastructure.

Key specifications

• Amperage: 225A
• Voltage: 600V
• Interrupting rating: 25kA
• Part number: JJA36225SA

Why this matters

Choosing the exact part number matters for safe operation and proper protection coordination. Using a matching JJA-series breaker helps maintain the panel’s intended electrical characteristics, reduces the risk of nuisance trips, and preserves the integrity of upstream protections. This is a drop-in option designed to align with Square D panel configurations that expect the JJA format.

Ideal use cases

• Retrofit projects where an existing 225A, 600V circuit needs a precise replacement
• Maintenance replacements to restore original protection levels and reliability
• Spare parts for service crews handling critical 600V distribution equipment

Before ordering, confirm fit and ratings to ensure compatibility with your specific Square D panel or switchgear. The JJA36225SA is the definitive reference for matching the exact specifications required in your installation.
