Square D HGA36125US 125A 3-Pole 600 V Circuit Breaker

Square D HGA36125US is a rugged three-pole circuit breaker engineered for demanding 3-phase power systems. With a 125 A current rating and a 600 V maximum, it delivers dependable overcurrent protection for medium-to-high load circuits in industrial and commercial electrical distributions.

• Part Number: HGA36125US
• Current rating: 125 A
• Poles: 3
• Voltage rating: 600 V

Designed for Square D panel systems, this 3-pole breaker provides balanced protection across all phases in 3-phase networks. The 125 A rating makes it suitable for feeders and downstream circuits that power motors, pumps, and other equipment common in commercial and light-industrial settings. The 600 V capability expands its applicability to higher-voltage distribution within compliant installations.

• Ideal for 3-phase equipment such as motors, conveyors, and HVAC systems that require synchronized phase protection.
• Replacement in compatible Square D panels where a 3-pole, 125 A, 600 V solution is specified.
• Reliable protection in standard electrical distributions across manufacturing floors, service entrances, and larger commercial installations.

To get the most from this breaker, ensure it’s installed in a compatible Square D panel designed for HGA-series devices and verify system voltage and load requirements align with the 125 A, 3-pole, 600 V specifications. This model brings a precise, straightforward solution for safeguarding three-phase circuits while supporting clear, coordinated tripping across all phases.
