Square D HDA260254AA 260254A 2-Pole 600 V Circuit Breaker Potential Transformer

Discover precise protection and measurement in one rugged package with the Square D HDA260254AA. This 2-pole, 600 V circuit breaker with an integrated potential transformer is designed for industrial and commercial panels where reliable fault isolation meets accurate electrical monitoring.

Why this unit stands out

• Two-pole protection: Interlocks both live conductors for coordinated tripping and enhanced safety in demanding electrical systems.
• 600 V voltage rating: Built to handle higher-voltage distribution environments, making it suitable for mid- to large-scale installations.
• Integrated potential transformer: Provides a low-voltage signal for precise current and voltage sensing, enabling accurate metering, energy management, and protective relays without extra wiring.
• Compact, panel-ready design: Engineered to fit standard enclosures and seamlessly pair with Square D panels and monitoring ecosystems.
• Part integrity: Identified by the part number HDA260254AA and associated with the 260254A family, ensuring you’re selecting a compatible, genuine component for maintenance or upgrades.

Ideal applications

• Electrical distribution panels in commercial buildings and light industrial facilities where both protection and metering are required.
• Motor control centers and feeder circuits that benefit from integrated sensing to streamline monitoring and relays.
• retrofit projects that aim to reduce wiring complexity by combining protection with a built-in sensing transformer.

Practical guidance and benefits

Choosing the HDA260254AA means you’re investing in a device that not only safeguards circuits but also simplifies measurement workflows. The built-in potential transformer delivers reliable secondary signals for energy meters and protective relays, helping you monitor load, detect abnormalities early, and coordinate protection strategies across the system. Its 2-pole design supports efficient control of multi-wire circuits, reducing wiring complexity and space requirements inside the panel.

Installation and maintenance considerations:

• Confirm your enclosure supports a 2-pole, 600 V device and that mounting hardware aligns with Square D standards.
• Verify compatibility with your existing monitoring or metering equipment to ensure seamless signal integration from the potential transformer.
• Keep records aligned with part identification (HDA260254AA / 260254A) for future replacements or upgrades.

For engineers and electricians seeking a dependable, integrative solution, the Square D HDA260254AA delivers protection plus precise electrical monitoring in a compact, field-ready package. It’s the right choice when you need robust circuit protection without sacrificing measurement accuracy or installation efficiency.
