Meet the Square D JGL36200—a rugged, reliable 200 A, 600 V, 3-pole molded case circuit breaker designed to guard your electrical systems with precision. Built for dependable branch circuit overcurrent and short-circuit protection, this unit fits neatly into panelboards and load centers, delivering consistent performance where it’s needed most.

Why this breaker stands out

• Compact molded-case design maximizes panel space, helping you fit in more circuits without crowding the bus or compromising access for servicing.
• Thermal-magnetic trip unit combines thermal overload protection with magnetic short-circuit protection, delivering stable, repeatable response across varying loads and fault conditions.
• Three-pole configuration ideal for 3-phase systems, providing balanced protection for all conductors in commercial or light industrial applications.
• 200 A rating at 600 V sets a solid protection point for feeders and critical circuits, reducing the risk of cascading faults in larger panel assemblies.
• OEM-compatible compatibility designed to work with matching Square D OEM load centers and panelboards, ensuring straightforward replacement or upgrade without compatibility concerns.
• Versatile across environments suitable for residential, commercial, and light industrial applications, giving you a single solution for multiple projects.

What problems it solves

In any panelboard or load center, a single fault can cascade into widespread downtime. The JGL36200 addresses this by:

• Providing fast, reliable protection against overloads and short circuits, helping to prevent damage to wiring and connected equipment.
• Maintaining panel organization and serviceability with a compact design that leaves room for future expansion.
• Offering consistent protection characteristics through a thermal-magnetic trip unit, reducing nuisance trips while preserving safety margins.

Ideal use cases

• Upgrading or replacing a 3-pole protective device in commercial or light industrial panelboards where a 200 A, 600 V rating is required.
• Installing a dependable feeder breaker in new construction or retrofit projects that use compatible OEM load centers.
• Protecting critical three-phase circuits in service entrances, machinery feeders, or distribution panels in small to mid-size facilities.
