Square D | HJA261502 | Circuit Breaker | 150A | 2-Pole | 600V | 25kA

Introducing the Square D HJA261502 circuit breaker—a reliable, high-capacity overcurrent protector engineered for demanding electrical systems. With a 150 A rating across 2 poles and a 600 V operating range, this unit delivers robust performance in commercial and industrial environments. Its 25 kA interrupting rating provides a strong margin for fault currents, helping safeguard wiring, devices, and personnel.

Designed for maintenance, retrofit, and replacement projects where exact specifications matter, the HJA261502 relies on a precise part number as the best reference for compatibility. Before ordering, verify that your equipment can accommodate 2-pole, 150 A protection at 600 V, and that the 25 kA rating aligns with your system faults.

• Amperage: 150 A
• Poles: 2-Pole
• Voltage: 600 V
• Interrupting rating: 25 kA
• Reference: Part number HJA261502 is your best compatibility guide

Who it's ideal for: professionals upgrading or replacing protective devices in commercial panels, service entrances, or industrial distribution systems where a solid, precise 2-pole breaker is required. It suits Square D installations and other environments where matching the exact part number ensures proper fit, bus connection, and reliable performance.

Practical benefits and use cases include:

• Replacing a failed or aging breaker in a 2-pole 600 V circuit
• Upgrading to a higher-capacity 150 A protection on feeder circuits
• Retrofitting legacy panels to meet higher fault-current demands without changing the entire panel

Tips for best results: always confirm fit and ratings against your panel labeling and the HJA261502 part number. Keep a copy of the panel's compatibility notes and cross-reference your panel manufacturer’s documentation to avoid mismatches. This approach minimizes downtime and maintains electrical safety during retrofit or replacement projects.
