HGL36040 - 40 Amp Circuit Breaker

HGL36040 - 40 Amp Circuit Breaker

The HGL36040 is a 40A, 3-pole PowerPacT H circuit breaker made for electrical distribution applications that need dependable overload and short-circuit protection. It uses a thermal-magnetic trip mechanism, a proven setup that responds to sustained overloads as well as higher-current fault conditions. Add in an 80% continuous-current rating, HACR rating, three-pole construction, and unit-mount design, and the HGL36040 is a sensible choice when those specific electrical and physical characteristics match the equipment you're working with.

Key Features and Benefits

• 40A, 3-pole design — suited to compatible three-pole distribution circuits.
• Thermal-magnetic trip protection — provides overload and short-circuit protection without an electronic trip unit.
• Line and load lugs — provide mechanical lug connections on both sides of the breaker.
• Dual-break rotating contacts — designed to reduce peak current during short-circuit faults.
• Built-in push-to-trip function — handy for manual testing and maintenance by qualified personnel.
• Cu/Al conductor compatibility — AL150HD terminals accommodate 14 AWG through 3/0 AWG copper or aluminum conductors.
• 80% continuous-current rating — clearly defined for applications designed around this rating.

Material Compliance and Certifications

The HGL36040 circuit breaker carries UL, CSA, and NOM certifications and is CE marked. Listed standards include UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2. The front cover has an IP40 degree of protection under IEC 60529, and the unit is classified as Pollution Degree 3 under IEC 60947-1.

Where It Works Best

The HGL36040 makes sense in compatible commercial, industrial, institutional, and facility electrical distribution systems where a 40A, three-pole thermal-magnetic circuit breaker is specified. Its 600VAC capability and mechanical line/load lug arrangement also make it relevant for installations that need this particular H-frame configuration.
