Introducing the Square D HLL36020AA Circuit Breaker—a purpose-built protection device engineered for reliability in maintenance, retrofit, and replacement projects where exact specifications matter. This is the 20A, 3-Pole, 600V solution that keeps three-phase systems safeguarded with precise coordination.
Key specifications in practical terms:
- Amperage: 20A per pole — balanced protection for each conductor in demanding three-phase loads.
- Poles: 3-Pole — ensures simultaneous interruption of all three lines, enhancing safety in three-phase circuits.
- Voltage rating: 600V — suitable for industrial and commercial equipment operating at higher voltages.
- Part reference: HLL36020AA — the best compatibility reference for precise fit and ratings.
- Brand trust: Square D — a long-standing standard in reliable electrical protection and panel compatibility.
Why this matters for your project
- Exact fit and dependable performance — using the exact part number minimizes guesswork, reduces field returns, and supports seamless integration into existing Square D installations.
- Three-phase safety — a three-pole design provides coordinated disconnection across all lines, which is critical for motors, compressors, and other three-phase equipment.
- Higher-voltage readiness — a 600V rating broadens applicability for commercial and industrial panels, allowing you to standardize protection across diverse gear.
Ideal use cases include maintenance and retrofit jobs where you’re upgrading or replacing worn breakers, panel modernization in Square D ecosystems, and upgrades to accommodate three-phase equipment without compromising protection. Before you order, confirm fit and ratings—the HLL36020AA part number is the most reliable reference for compatibility.
Installation and safety notes
- Professional installation is recommended. Always power down the system and follow local electrical codes during replacement or upgrading work.
- Cross-check panel requirements and confirm that a 3-Pole, 20A, 600V device matches your panelboard’s specifications and wiring configuration.
