HGA36040 - 40 Amp Circuit Breaker

HGA36040 - 40 Amp Circuit Breaker

The HGA36040 PowerPacT H circuit breaker is a 40-amp, 3-pole breaker designed for electrical distribution systems that need reliable thermal-magnetic protection. It helps protect your circuits from overloads and short circuits and carries an 18 kA interrupting rating at 600VAC, with higher ratings at lower AC voltages. With its 40A rating, 3-pole configuration, 80% continuous-current rating, ABC phase connection, and HACR rating, the HGA36040 is a strong choice for replacement and maintenance work where these exact electrical requirements are needed.

Key Features and Benefits

• 40A, 3-pole design – Built for three-pole distribution applications that call for a 40-amp breaker.
• Thermal-magnetic protection – Provides overload and short-circuit protection without an electronic trip unit.
• I-Line connection – Designed for compatible I-Line equipment, with mechanical lugs on the load side.
• Dual-break rotating contacts – Helps limit peak current during short-circuit conditions.
• Push-to-trip button – Makes manual tripping straightforward 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 HGA36040 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 HGA36040 is a good fit for commercial, industrial, institutional, and facility electrical systems that use compatible I-Line equipment. It is especially useful when the application calls for a 40A, 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.
