HGL36150 - 150 Amp Circuit Breaker

HGL36150 - 150 Amp Circuit Breaker

When you need dependable three-pole protection for heavy duty electrical systems, the HGL36150 delivers. This 150 A circuit breaker is engineered to guard industrial and commercial installations against overloads and short circuits with precision and confidence. Built on the PowerPacT H-Frame platform, it offers a breaking capacity of 18 kA at 600 V AC — and can handle even higher fault levels at lower voltages (for example, 35 kA at 480 V AC) — making it a solid choice for demanding high-current setups. Field-installable accessories and convertible busbar or lug options mean you get flexibility at installation time, and the front-facing semi-transparent cover provides quick visual status checks so your maintenance team can stay ahead. With compliance to UL, CSA, IEC and global certifications, the HGL36150 gives you performance you can count on.

Key Features and Benefits

• Thermal-magnetic protection in each pole: Combines thermal trip for long-term overloads with magnetic trip for short-circuit events, giving you broad protection under varying load conditions.
• Installation flexibility: Busbar or lug connections can be converted on-site thanks to snap-in terminals, helping reduce inventory and tailor to your wiring method.
• Easy visual inspection: The front-facing semi-transparent cover lets technicians quickly check status without disassembly, cutting down on maintenance time.
• High interrupting capacity: Rated for 18 kA at 600 V AC and higher at other voltages, this breaker can safely interrupt substantial fault currents, giving your system an extra margin of safety.
• Global-ready certification: Recognised by UL, CSA, NOM and IEC standards, and CE-marked, so you’re covered in industrial, commercial and utility environments worldwide.

Where It Works Best

• The HGL36150 is ideal for high demand environments such as industrial manufacturing plants, commercial building power-distribution panels, and utility installations where load capacity is large and fault potential is significant. If you’re working with large motors, HVAC systems, heavy lighting loads or mission-critical backup power systems — and you need a breaker that can both protect and perform under surge conditions — this unit delivers. It’s especially useful where you want flexibility in installation (busbar or lug) and require visual status indication without dismantling the breaker.
