HGA36110 - 110 Amp Circuit Breaker

HGA36110 - 110 Amp Circuit Breaker

When the job calls for a 110-amp, 3-pole I-Line circuit breaker, the details matter. The HGA36110 PowerPacT H uses thermal-magnetic trip protection to help protect electrical distribution systems against overloads and short circuits. Its interrupting capacity is 18 kA at 600VAC, with UL 489 ratings of 35 kA at 480VAC and 65 kA at 240VAC. Whether you’re replacing an existing breaker or matching components for compatible distribution equipment, the HGA36110 gives you a clearly defined set of electrical, mounting, and connection specifications to work from.

Key Features and Benefits

• 110A, 3-pole design – Made for distribution applications that specifically require a 110-amp, three-pole breaker.
• Thermal-magnetic trip unit – Provides straightforward overload and short-circuit protection.
• I-Line mounting configuration – Designed for use with compatible I-Line distribution equipment.
• Mechanical load-side lugs – Accept both aluminum and copper conductors across a broad size range.
• Dual-break rotating contacts – Help reduce peak current during short-circuit faults.
• Built-in push-to-trip button – Allows qualified technicians to manually trip the breaker when required.
• 80% continuous-current rating – Uses an ABC phase connection.
