Square D HLA36070SLYP 70A 3-Pole 600 V Circuit Breaker

The Square D HLA36070SLYP 70A 3-Pole 600 V Circuit Breaker is a rugged, three-phase protection device designed for demanding electrical systems. With a 70-amp current rating and a 3-pole configuration, it provides reliable safeguarding for your 600 V distribution setups, helping prevent overloads and short circuits across all phases.

Key features that matter in real-world installations:

• Current rating: 70 A — configured to protect moderately high-demand circuits without nuisance tripping.
• Poles: 3 — ideal for three-phase power distribution, ensuring coordinated protection across all phases.
• Voltage rating: 600 V — suitable for commercial and light industrial applications that operate at or below this level.
• Part number: HLA36070SLYP — precise ordering and easy replacement within Square D systems.

Why this model stands out in its class

• Designed for compatibility with Square D panelboards and systems that accept HLA-series breakers, delivering consistent electrical protection within established Square D infrastructure.
• Three-pole construction protects all phases in 3-phase equipment such as motors, pumps, conveyors, and other industrial loads, helping maintain balanced operation and reducing the risk of uneven phase failures.
• Clear, straightforward replacement path: when a breaker needs replacement, choosing the same part number ensures fit, alignments, and trip characteristics align with your existing protection scheme.

Practical use cases and scenarios

• Three-phase motor circuits in manufacturing lines where reliable interruption is essential to prevent equipment damage and downtime.
• Panelboard protection for HVAC systems, pumps, and processing equipment that run on 600 V or within the rated range of three-phase distribution.
• Upgrade or maintenance projects where a matching Square D component is required to preserve electrical coordination and labeling in the distribution network.

Tips for optimal results

• Verify that your panel accepts HLA-series breakers before installation to ensure proper fit and electrical coordination.
• Inspect the surrounding wiring and lugs for clean, secure connections to maintain reliable performance over time.
• Keep a record of the part number (HLA36070SLYP) for future replacements or service planning, ensuring consistent protection across upgrades.

If you’re protecting a three-phase 600 V distribution network and need a dependable, easy-to-replace solution, the Square D HLA36070SLYP 70A 3-Pole 600 V Circuit Breaker delivers targeted protection with straightforward maintenance and compatibility within established Square D systems.
