Key advantages

• Compact molded case design maximizes panel space while delivering solid protection, making it ideal for installations where space is at a premium.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to both overload and short-circuit conditions, reducing nuisance trips and protecting downstream equipment.
• 3-pole configuration supports three-phase systems, providing coordinated protection for modern commercial and light industrial layouts.
• OEM-compatible designed to pair with matching Square D loadcenters and panelboards for a reliable, code-compliant fit and straightforward installation.
• Versatile application suitable for residential, commercial, and light industrial environments where dependable branch circuit protection is essential.

Practical use cases

• Protect three-phase feeders in commercial spaces such as small offices, retail storefronts, or light manufacturing facilities.
• Upgrade or retrofit panelboards in existing installations where a high-amperage, space-efficient solution is needed.
• Integral protection for main distribution panels, subpanels, and load centers that require consistent trip performance across varying loads and temperatures.

Why choose the Square D JLL36225

Rather than a one-size-fits-all breaker, this unit emphasizes precise coordination with Square D panel systems, ensuring compatibility and predictable operation. The thermal-magnetic technology provides a reliable balance between fast short-circuit clearing and minimizing unnecessary trips during temporary surges. Its 225 A rating and 600 V capacity cover a broad range of distribution scenarios, while the 3-pole design aligns with modern three-phase electrical distributions found in many commercial and light industrial settings.
