Square D HDA260254AABCSDYP 260254A 3-Pole 600 V Circuit Breaker Potential Transformer

Square D HDA260254AABCSDYP is a three‑pole, 600 V circuit breaker variant designed for demanding industrial power systems. This model blends established Square D protection with potential transformer (PT) compatibility, delivering not only reliable overcurrent protection but also streamlined monitoring and metering integration for modern control schemes.

Key benefits

• Three-pole configuration supports balanced protection for three‑phase systems, ensuring uniform operation across all phases.
• 600 V maximum system voltage makes it suitable for a wide range of industrial panels, switchgear, and distribution applications.
• Part number specificity (HDA260254AABCSDYP) simplifies ordering, stocking, and cross‑reference within Square D/Schneider Electric ecosystems.
• Potential transformer readiness allows compatible metering and protection relays to read accurate voltage signals with reduced wiring complexity.
• Designed for seamless integration in existing Square D panels and devices, helping minimize downtime during upgrades or replacements.

Where it shines

Use this device in service entrance and feeder panels, industrial machinery enclosures, or data center infrastructure where robust three‑phase protection and measurement readiness are required. The 3‑pole format is ideal for three‑phase drives, motors, and power distribution networks, while PT compatibility supports precise voltage sensing for protection relays and energy meters.

Practical considerations

• Ensure your system voltage aligns with the 600 V rating and confirm the specific ampacity from the official datasheet for this exact part code.
• Verify enclosure compatibility and mounting arrangement with your existing Square D equipment to maintain consistent operating clearances.
• Plan for PT-related connections when configuring metering or protection relays to take full advantage of the transformer‑aware design.

For professionals building or upgrading industrial power protection, the Square D HDA260254AABCSDYP stands out as a purpose-built solution that pairs reliable three‑phase protection with thoughtful compatibility for potential transformer monitoring.
