Square D HLL36050 - 50 A, 600 V, 3-Pole Circuit Breaker | AmpState

Introducing the Square D HLL36050 — a 3-pole molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. With a 50 A rating and a 600 V maximum, it’s built to handle the demands of both residential setups and light commercial or industrial projects.

• Compact molded-case design — optimizes panel space for cleaner layouts and easier panel planning, helping you fit more protection without sacrificing performance.
• Thermal-magnetic trip unit — provides stable, repeatable protection by combining heat-based sensing for sustained overloads with magnetic action for immediate response to high-current faults.
• 3-pole configuration — synchronized protection across three phases, ideal for 3-phase equipment and feeder circuits in commercial and light industrial panels.
• 50 A, 600 V rating — versatile for a range of branch circuits and higher voltage applications, expanding the utility of a single device across multiple panel types.
• OEM-compatible — designed to pair seamlessly with matching Square D load centers and panelboards, ensuring a straightforward replacement experience and consistent performance within the same panel family.
• Practical reliability — purpose-built for residential, commercial, and light industrial use, offering predictable trip behavior and robust protection for everyday circuits and demanding loads alike.

The HLL36050 stands out by delivering a compact footprint without compromising protection quality. Its thermal-magnetic trip mechanism reduces nuisance trips while still delivering fast interruption during short circuits, keeping wiring and connected equipment safer. This makes it an excellent choice when upgrading or expanding a Square D system where panel space is at a premium and reliable protection across all three phases is required.

Key use cases include protecting branch circuits feeding lighting, outlets, and modest electrical loads in homes, small offices, retail environments, and light industrial spaces. It’s also well-suited for feeders to motors and other equipment in panelboards that demand consistent, coordinated protection across phases. If you’re stocking Square D components for OEM panels or performing panel refreshes, the HLL36050 provides a dependable, compatible option that aligns with existing equipment and infrastructure.
