HGA36050 - 50 Amp Circuit Breaker

HGA36050 - 50 Amp Circuit Breaker

The HGA36050 PowerPacT H circuit breaker is a 50-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 higher interrupting ratings at lower voltages. The HGA36050 also carries an 80% continuous-current rating, uses an ABC phase connection, and is HACR rated for qualifying heating, air-conditioning, and refrigeration applications. If your application calls for a 50A, 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

• 50A, 3-pole design – Built for three-pole electrical distribution applications requiring a 50-amp breaker.
• Thermal-magnetic protection – Handles overload and short-circuit protection without an electronic trip unit.
• I-Line construction – Designed for compatible I-Line equipment, with mechanical lugs on the load side.
• Dual-break rotating contacts – Helps reduce peak current during short-circuit conditions.
• Push-to-trip button – Makes manual tripping easy for qualified technicians.
• 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 HGA36050 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 HGA36050 fits best in commercial, industrial, institutional, and facility electrical systems that use compatible I-Line equipment. It is especially useful when the application calls for a 50A, 3-pole thermal-magnetic breaker with an 18 kA interrupting rating at 600VAC.
Its 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.
