Square D HGL36030 - 30 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Square D HGL36030—a compact, reliable 3-pole molded-case circuit breaker designed to protect your panelboards and loadcenters from overcurrent and short circuits. With a 30A rating and a 600V maximum, this unit is built for demanding three‑phase systems while conserving valuable panel space.

• Space‑efficient molded‑case design: Optimizes panel layouts, helping you fit more protective devices into the same footprint without sacrificing reliability.
• Thermal‑magnetic trip unit: Delivers stable, repeatable protection by automatically responding to overloads and instantly interrupting severe short circuits for safer, more predictable performance.
• 3‑pole configuration: Disconnects all three live conductors in a 3‑phase circuit simultaneously, ensuring coordinated protection for motors, compressors, and other multi‑phase equipment.
• 30A @ 600V: Suited for branch circuits powering moderate-load equipment in residential, commercial, and light industrial environments.
• OEM‑alignment: Designed to work with matching Square D loadcenters and panelboards, preserving fit, function, and system coordination.

Typical scenarios where the HGL36030 shines include protecting motors in HVAC systems, controlling lighting and receptacle circuits in commercial spaces, or safeguarding small industrial equipment where reliable fault protection is essential. The 3‑pole design is ideal for three‑phase distributions, delivering comprehensive protection across all lines in one compact unit.

Why choose this unit? It combines a compact form with a robust thermal‑magnetic mechanism, offering predictable tripping behavior and straightforward integration into compatible Square D panelboards. Its 30A rating makes it a precise choice for protecting branch circuits that don’t require higher amperage, while the 600V rating accommodates a wide range of industrial and building applications.

Practical tips for getting the most from your breaker: verify the panelboard compatibility with your Square D system, correctly torque connections to the manufacturer’s specifications, and coordinate with other protective devices to ensure coordinated protection across the panel. For reliable, long‑term performance, pair this breaker with a matching loadcenter and follow standard electrical codes during installation.
