Square D | HJA261501 | Circuit Breaker | 2-Pole | 25kA

The Square D HJA261501 Circuit Breaker is a precise, two-pole solution built to protect your electrical system with a robust 25kA interrupting capacity. Designed for reliability, it fits maintenance, retrofit, and replacement projects where exact compatibility matters, delivering dependable protection for both live conductors in your panel.

Key features and references at a glance:

• Poles: 2-Pole — ensures simultaneous disconnection of both hot legs for enhanced safety and coordinated tripping
• Interrupting rating: 25kA — suitable for circuits and fault conditions within this capacity range
• Part number reference: HJA261501 — the most reliable basis for compatibility checks
• Brand alignment: Square D — designed to integrate with Square D panels and bus configurations

Why this breaker stands out

Unlike generic replacements, this unit is purpose-built for Square D electrical systems. The HJA261501 designation signals exact fit, performance characteristics, and plug-in compatibility with panels that accept this specific model. This means fewer surprises during installation, smoother circuit protection, and clearer maintenance documentation for your electrical system.

Ideal use cases

• Replacement when a 2-pole breaker in a Square D panel has failed or degraded performance
• Retrofit projects where a 2-pole, 25kA capable device is required to upgrade protection without changing the panel
• Maintenance cycles that demand a dependable, readily identifiable part number for quick ordering and cross-referencing

How to verify compatibility (without guesswork)

Before ordering, confirm fit and ratings by cross-referencing with your panel’s documentation. The part number HJA261501 is the strongest compatibility signal—the best reference for ensuring the breaker will drop into your Square D system. Always check that the panel accepts this exact model and that the installation aligns with the panel’s labeling and protective coordination requirements.

Practical tips for installation and aftercare

• Keep a few HJA261501 units on hand for planned maintenance and quick replacements
• Store in a dry, clean workspace to preserve contacts and mechanism integrity
• During installation, follow standard safety procedures and verify that the main power is de-energized before handling breakers
