HGA36100 - 100 Amp Circuit Breaker

HGA36100 - 100 Amp Circuit Breaker

The HGA36100 PowerPacT H circuit breaker is a 100-amp, 3-pole breaker made for electrical distribution systems that need dependable overload and short-circuit protection. It uses thermal-magnetic trip technology and is rated 18 kA at 600VAC, with additional interrupting ratings of 35 kA at 480VAC and 65 kA at 240VAC under UL 489. If your job calls for a 100A, 3-pole I-Line breaker with these exact ratings, this model is a practical fit for maintenance, replacement, and compatible distribution-system work.

Key Features and Benefits

• 100A, 3-pole design – Built for three-pole distribution applications that require a 100-amp breaker.
• Thermal-magnetic trip protection – Handles overload and short-circuit protection without an electronic trip unit.
• I-Line configuration – Uses an I-Line line-side connection with mechanical lugs on the load side.
• Dual-break rotating contacts – Helps limit peak current during short-circuit conditions.
• Push-to-trip button – Gives qualified personnel a simple manual trip function.
• 80% continuous-current rating – Configured with an ABC phase connection.
• Wide conductor range – AL150HD terminals accept 14 AWG through 3/0 AWG aluminum or copper conductors.

Material Compliance and Certifications

The HGA36100 carries UL, CSA, and NOM certifications and is CE marked. It also meets applicable UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2 standards. The front cover is rated IP40 under IEC 60529, and the breaker is classified for Pollution Degree 3 under IEC 60947-1.

Where It Works Best

The HGA36100 is a good fit for commercial, industrial, institutional, and facility electrical systems that use compatible I-Line equipment. It is especially useful where the application calls for a 100A, 3-pole thermal-magnetic breaker with an 18 kA interrupting rating at 600VAC.
The I-Line line-side connection can make replacement work more convenient in compatible equipment, while the mechanical load-side lugs give installers flexibility with both aluminum and copper conductors. Its HACR rating also makes it suitable for qualifying HVAC and refrigeration applications.
