ABB XT1NU3020AFD000XXX 20A 3P 480V Circuit Breaker, Bolt-On | AmpState

Meet the ABB XT1NU3020AFD000XXX — a 20 A, 3-pole bolt-on circuit breaker engineered for robust circuit protection in panelboards, load centers, and electrical distribution systems.

Designed for retrofit work and maintenance planning, this ABB part keeps your inventory simple with a consistent part number, making replacements straightforward even when updating aging panels.

• Bolt-on mounting: fast, secure installation onto compatible ABB panelboards with minimal hardware and downtime, delivering a solid, vibration-resistant connection.
• Three-phase protection: 3 poles ensure reliable sharing of current across all phases in a 3-phase system, helping prevent unbalanced loads.
• 20 Ampere rating: precise overcurrent protection for branch circuits and equipment in industrial and commercial environments.
• 480 Volt system compatibility: suitable for high-voltage distribution setups common in commercial and industrial facilities.
• XT1NU family compatibility: part of ABB's XT1NU line, designed for dependable performance in common panelboard configurations.
• Part number consistency: ideal for retrofit projects where inventory and ordering accuracy matters; your maintenance plans stay aligned with a single, traceable SKU.
• AmpState availability: currently available from AmpState, with support to confirm fit if needed.

This breaker is ideal for facilities that run three-phase power—manufacturing floors, data centers, and large commercial buildings—where downtime is costly and space is at a premium. Use cases include replacing a failed breaker in an ABB panel, upgrading protection in existing distributions, or stocking a reliable, easy-to-order component for planned maintenance cycles.

How it compares to other options: while many breakers offer similar current and voltage ratings, the XT1NU3020AFD000XXX delivers a bolt-on design coupled with ABB's trusted XT1NU platform, reducing installation complexity and ensuring compatibility with your existing panel architecture. Its 3-pole configuration matches standard three-phase feeders, simplifying replacement without reconfiguration.

Compatibility and installation tips: verify your panelboard accepts XT1NU 3-pole bolt-on breakers, align with bus bars, and follow standard ABB installation guidelines to ensure reliable operation and trip protection. For retrofit planning, keep the XT1NU3020AFD000XXX in stock to maintain consistent part numbers across your service fleet.
