HGA36090 - 90 Amp Circuit Breaker

HGA36090 - 90 Amp Circuit Breaker

When you’re replacing a circuit breaker, the details have to line up. The HGA36090 PowerPacT H is a 90A, 3-pole I-Line circuit breaker with thermal-magnetic trip protection for overload and short-circuit conditions. With an 80% continuous-current rating, ABC phase connection, HACR rating, and terminals that accommodate both aluminum and copper conductors, the HGA36090 covers the key requirements for a variety of commercial and industrial distribution applications. If you're replacing an existing breaker, matching the full catalog number and electrical specifications is the smart place to start.

Key Features and Benefits

• 90A, 3-pole breaker – A straightforward choice when the application specifically requires 90 amps across three poles.
• Thermal-magnetic trip unit – Provides overload and short-circuit protection without an electronic trip system.
• I-Line connection – Designed to fit compatible I-Line distribution equipment.
• Mechanical load-side lugs – Accommodate aluminum and copper conductors from 14 AWG through 3/0 AWG.
• Dual-break rotating contacts – Designed to reduce the amount of peak current during a short-circuit fault.
• Push-to-trip function – A built-in button lets qualified technicians manually trip the breaker when required.
• 80% continuous-current rating – Uses an ABC phase connection.

Material Compliance and Certifications

The HGA36090 carries UL, CSA, and NOM certifications and is CE marked. Applicable standards include UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2. Its front cover has an IP40 protection rating according to IEC 60529, with a Pollution Degree 3 classification under IEC 60947-1.

Where It Works Best

The HGA36090 90A circuit breaker is intended for compatible I-Line electrical distribution equipment and can be a good fit for commercial facilities, industrial installations, institutional buildings, and similar three-phase distribution applications. It's particularly relevant when the job calls for a 90-amp, 3-pole thermal-magnetic I-Line breaker rated 18 kA at 600VAC.
It also makes sense for qualifying HACR applications involving heating, air-conditioning, or refrigeration equipment. The combination of an I-Line line-side connection and mechanical load-side lugs is useful when servicing compatible existing distribution equipment.
