Square D PGL36100 - 1000 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Square D PGL36100 — a rugged 3-pole molded case circuit breaker engineered for dependable branch circuit protection in panelboards and loadcenters. With a 1000A rating and a 600V capacity, this device is built to handle demanding commercial and light industrial environments, while still fitting into larger residential panel setups when needed.

Why this breaker stands out

• High-current capability — 1000A amperage rating powers large feeders and distribution paths, reducing the number of devices required in a single panel and enabling more efficient layouts.
• Thermal-magnetic trip unit — provides stable, repeatable protection by sensing both overload and short-circuit conditions, delivering fast response without nuisance trips across varying temperatures and loads.
• Compact molded case design — optimized for space in panelboards and loadcenters, helping you maximize panel capacity without sacrificing protection.
• Three-pole configuration — ideal for three-phase systems common in commercial and light industrial applications, ensuring coordinated protection across all phases.
• OEM compatibility — designed to match Square D OEM loadcenters and panelboards, simplifying replacement, wiring compatibility, and efficiency in service upgrades.
• Voltage rating — rated up to 600V, suitable for typical building distribution circuits and industrial installations demanding reliable interruption protection.
• Versatile applications — suitable for residential, commercial, and light industrial environments that require robust branch-circuit overcurrent and short-circuit protection.
