Square D HLA36070UP 70A 3-Pole 600 V Circuit Breaker

Square D HLA36070UP is a purpose-built circuit breaker engineered for reliable protection of three‑phase electrical systems. With a 70 A current rating, 3 poles, and a 600 V maximum voltage, this unit is ready to safeguard feeders and motors in demanding commercial and light industrial environments. Part number: HLA36070UP.

Designed to match Square D panels and distribution setups, the HLA36070UP delivers precise trip performance and straightforward replacement in busy electrical rooms. Its three-pole configuration ensures balanced protection across all three phases, helping prevent equipment damage, unplanned downtime, and nuisance trips on three‑phase loads.

Key benefits and why it matters

• Three-phase protection—optimizes safety for motors, compressors, conveyors, and other 3‑phase equipment by monitoring all conductors simultaneously.
• 70 A rating—provides appropriate protection for medium‑sized branch circuits and feeders without oversizing the protection device.
• 600 V voltage rating—suitable for a wide range of commercial and light industrial power distribution applications.
• Specific part identity—clear part number HLA36070UP for easy ordering, replacement, and panel compatibility.
• Reliable, brand-aligned performance—built to integrate with Square D equipment and typical electrical distribution environments, reducing compatibility concerns.

Ideal uses and practical scenarios

• Protect three-phase motor circuits in HVAC systems, pumps, or material handling equipment where up to 70 A per phase is typical.
• Feed branch circuits in commercial panels that power three-phase equipment, ensuring coordinated protection across L1, L2, and L3.
• Upgrade or retrofit existing 3‑phase setups that require a 600 V rating and a robust 3‑pole solution for dependable overload and short-circuit protection.

Installation, compatibility, and best practices

Before installation, verify that your panel supports the HLA series and that the circuit breaker’s voltage and current ratings align with your system. Ensure wiring is sized appropriately for 70 A and that terminals are torqued per your panel manufacturer’s guidelines. When replacing an existing breaker, confirm that the new unit’s trip characteristics match the protection needs of the connected loads to maintain coordinated protection across the distribution network.

What you gain with the HLA36070UP

• Enhanced safety for three-phase equipment and workflows, reducing the risk of overheating and unplanned outages.
• Dedicated 3‑pole protection that maintains balance across all phases, supporting reliable motor startup and operation.
• Clear part identification for efficient procurement and maintenance cycles, minimizing downtime caused by mis-orders.

For engineers and technicians managing commercial or light industrial power distribution, the Square D HLA36070UP offers a precise, dependable solution for three-phase protection up to 600 V, with a 70 A capacity that aligns with mid-range feeders and motor loads. This is the right choice when you need an exact-fit, high-visibility circuit breaker that integrates smoothly into your Square D ecosystem and supports consistent, safe operation of your three-phase equipment.
