Square D PGL36100U41 A - 1000 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Square D PGL36100U41A—a heavy‑duty 1000 A, 600 V, 3‑pole molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers. Its compact footprint frees up valuable panel space while delivering robust overcurrent and short‑circuit protection for demanding electrical installations.

Why this breaker stands out

• Space‑efficient molded case design: Maximizes wiring room and panel density without compromising protection performance.
• Thermal‑magnetic trip unit: Combines thermal sensing for sustained overloads with a magnetic trip for instantaneous response to high fault currents, delivering stable, repeatable protection and fewer nuisance trips.
• 3‑pole configuration for 3‑phase systems: Provides coordinated protection across all phases with compatibility for common trip in appropriate panel setups.
• OEM‑level compatibility: Specifically designed to integrate with matching Square D load centers and panelboards, ensuring proper fit, trip curves, and wiring layout.
• High current capability: 1000 A rating makes it suitable for main feeder protection and large branch circuits in commercial and light industrial environments.

Ideal applications and use cases

This breaker is well suited for panelboards and load centers in residential, commercial, and light industrial settings where large‑current protection is required. Use it to upgrade or replace existing protection for high‑demand circuits, or to expand a square D‑based distribution panel with reliable, predictable tripping behavior across all phases.
