HGL36020 - 20 Amp Circuit Breaker

HGL36020 - 20 Amp Circuit Breaker

When you’re matching a breaker to an existing electrical system, the details matter. The HGL36020 is a 20A, 3-pole PowerPacT H circuit breaker designed for electrical distribution applications where thermal-magnetic overload and short-circuit protection are required. It offers an 18 kA interrupting capacity at 600VAC, along with ratings of 35 kA at 480VAC and 65 kA at 240VAC under UL 489. The breaker uses dual-break rotating contacts to help limit peak current during a short-circuit fault, and a built-in push-to-trip button provides a convenient way for qualified personnel to manually trip the breaker when needed.

Key Features and Benefits

• 20A, 3-pole design for compatible three-pole electrical distribution systems.
• Thermal-magnetic protection responds to both overload and short-circuit conditions.
• Dual-break rotating contacts help reduce peak current during a short-circuit event.
• Line and load lugs provide a straightforward connection arrangement for unit-mount installations.
• 14 AWG to 3/0 AWG conductor range accommodates both copper and aluminum wiring.
• Built-in push-to-trip button makes manual tripping accessible for qualified personnel during testing or service.
• 80% continuous-current rating for applications designed around this rating.

Material Compliance and Certifications

The HGL36020 meets several widely recognized electrical safety and performance requirements. It carries UL, CSA, and NOM certifications and is CE marked. Applicable standards include UL, CSA, NEMA, NOM-003-SCFI-2000, and IEC 60947-2. The front cover carries an IP40 rating under IEC 60529, while the breaker is classified for Pollution Degree 3 according to IEC 60947-1.

Where It Works Best

The HGL36020 20A 3-pole circuit breaker makes the most sense in compatible commercial, industrial, and facility electrical distribution equipment requiring thermal-magnetic protection and a unit-mount breaker with line- and load-side lugs. It’s particularly well suited to applications calling for an 18 kA interrupting rating at 600VAC. The broad 14 AWG through 3/0 AWG Cu/Al terminal range also provides useful wiring flexibility.
