HGA36020 - 20 Amp Circuit Breaker

HGA36020 - 20 Amp Circuit Breaker

The HGA36020 PowerPacT H circuit breaker is a 20-amp, 3-pole breaker designed for use in electrical distribution systems that require thermal-magnetic protection. It helps protect your connected equipment and conductors from overloads and short circuits, while its 18 kA interrupting rating at 600VAC makes it suitable for demanding commercial and industrial applications.

Key Features and Benefits

• 20A, 3-pole design – Made for three-pole distribution applications that call for a 20-amp breaker.
• Thermal-magnetic protection – Provides dependable overload and short-circuit protection without an electronic trip unit.
• I-Line connection – Designed for compatible I-Line equipment, with line-side I-Line mounting and load-side mechanical lugs.
• Dual-break rotating contacts – Helps limit peak current during short-circuit conditions.
• Push-to-trip button – Lets technicians manually trip the breaker from the front cover.
• 80% continuous-current rating – Suitable for applications designed around its listed continuous load rating.
• Wide conductor range – Accepts 14 AWG through 3/0 AWG aluminum or copper conductors.

Material Compliance and Certifications

The HGA36020 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 according to IEC 60947-1.

For maintenance teams and electrical contractors, those certifications make it easier to confirm whether the breaker fits the requirements of a given system. Still, the catalog number and electrical ratings should always be checked against the equipment before installation.

Where It Works Best

The HGA36020 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 20A, 3-pole thermal-magnetic breaker with an 18 kA interrupting rating at 600VAC.

Its I-Line construction can make installation and replacement more convenient in compatible equipment, while the mechanical load-side lugs give installers flexibility with both aluminum and copper conductors. The HACR rating also makes it useful in qualifying heating, air-conditioning, and refrigeration applications.
