Square D HGL36150U44X - 150A, 3-Pole Molded Case Circuit Breaker is built to protect your panelboards and loadcenters with precision, reliability, and space-saving efficiency. Designed for dependable branch circuit overcurrent and short-circuit protection, this 3-pole breaker is a smart choice for modern electrical installations across residential, commercial, and light industrial settings. Key benefits and why it matters - Space-conscious molded case design: The compact form factor helps you maximize panel space without compromising protection, making it ideal for crowded electrical rooms or retrofit projects where every inch counts. - Thermal-magnetic trip unit: Combines precise thermal overload protection with fast magnetic tripping for short circuits. The result is stable, repeatable protection performance that minimizes nuisance trips while safeguarding equipment and wiring. - 3-Pole configuration for 3-phase systems: Perfect for three-phase branch circuits common in commercial and light-industrial environments, ensuring coordinated protection across all live conductors. - OEM-ready compatibility: Engineered to fit and function with matching Square D OEM loadcenters and panelboards, supporting seamless installation, consistent electrical coordination, and straightforward replacement. - Versatile application spectrum: From new panel builds to upgrades and service changes, it reliably protects circuits in homes, offices, retail spaces, and small industrial facilities. What makes this unit unique - Precise coordination with Square D ecosystems: By aligning with the same family of panelboards and loadcenters, the HGL36150U44X minimizes compatibility headaches and keeps your electrical system running smoothly. - Durable, field-ready construction: Built to endure the demands of daily operation in busy electrical rooms, with a design that emphasizes longevity and dependable performance under varying temperatures and loads. - Clear path to safer, simpler maintenance: With a clear trip mechanism and predictable response, maintenance teams can diagnose and verify protection quickly, reducing downtime during inspections or panel servicing. Practical use cases - Upgrading an aging panel to accommodate higher loads in a small commercial space. - Replacing a failed or mismatched breaker in a Square D panelboard within a retail or light industrial environment. - Installing a dedicated 150A, 3-phase feeder in a new construction project where space efficiency and reliable protection are priorities. Technical snapshot - Manufacturer: Square D - Part Number: HGL36150U44X - Type: Thermal-magnetic molded case circuit breaker - Amperage Rating: 150A - Number of Poles: 3 - Application: Branch circuit overcurrent and short-circuit protection How this breaker compares to typical options - If you’re balancing space constraints with the need for robust protection, this unit’s molded-case design delivers both, unlike bulkier breakers that consume more panel real estate. - The thermal-magnetic trip unit provides a balanced protection profile—sensitive enough to trip quickly on dangerous short circuits, yet forgiving during normal inrush events—reducing unnecessary interruptions. In short, the Square D HGL36150U44X is a purpose-built, space-efficient, and dependable choice for safeguarding three-phase branch circuits in panelboards and loadcenters. It brings precise protection, compatibility, and practical flexibility to residential, commercial, and light industrial electrical projects.
