Direct-fit performance for Square D systems

The JGA36250 is designed as a direct part-number match for Square D installations, reducing guesswork during replacements and spare-stock planning. Its 3-pole construction supports three-phase distribution, protecting feeders and equipment across commercial and light-industrial settings. With a 250 A rating and a 600 V maximum, it provides robust protection for higher-current circuits while staying compatible with common Square D panelboards and load centers.

Why professional teams choose JGA36250

• Precise compatibility: direct part-number match minimizes installation issues and downtime.
• Three-pole protection: ideal for three-phase distribution systems common in offices, data centers, and small industrial applications.
• High-current control: 250 A capacity shields wiring and devices from overloads without nuisance tripping on normal transients.
• Versatile installation: suitable for panelboards and electrical distribution setups that require 600 V-rated protection.
• Inventory-friendly: reliable spare in maintenance vans and service fleets, ensuring fast replacements.
• Support from AmpState: help confirming fit if you’re unsure about compatibility with your existing panels.

Practical use cases

Keep on hand as a ready-to-swap main breaker in 3-phase panelboards, or use during panel upgrades and retrofits where a direct JGA-series replacement is preferred. In service contracts or facility management programs, carrying the JGA36250 helps shorten downtime during fault events or routine maintenance.

What sets it apart

Unlike generic replacements, the JGA36250 is a true Square D part designed to integrate with their distribution equipment without modification. It minimizes compatibility risk and simplifies inventory management by offering a straightforward, direct-fit option for key Square D installations.
