HGL36070 - 70 Amp Circuit Breaker

HGL36070 - 70 Amp Circuit Breaker

The HGL36070 is a 70A, 3-pole PowerPacT H circuit breaker built for your electrical distribution applications where dependable overload and short-circuit protection matters. It uses a thermal-magnetic trip unit and provides an interrupting capacity of 18 kA at 600VAC, along with 35 kA at 480VAC and 65 kA at 240VAC under UL 489.

Key Features and Benefits

• 70A, 3-pole configuration: Designed for compatible three-pole electrical distribution systems requiring a 70-amp breaker.
• Thermal-magnetic trip protection: Provides overload and short-circuit protection without the complexity of an electronic trip unit.
• Dual-break rotating contacts: Help reduce peak current during a short-circuit fault.
• Line and load lugs included: Mechanical lug connections on both sides make this model well suited to unit-mount installations.
• Wide conductor range: AL150HD terminals accommodate 14 AWG through 3/0 AWG copper or aluminum conductors.
• Built-in push-to-trip button: Allows qualified personnel to manually operate the trip mechanism for testing or service procedures.
• 80% continuous-current rating: Clearly defined for applications designed around an 80% rated breaker.

Material Compliance and Certifications

The HGL36070 circuit breaker is manufactured to meet recognized electrical standards for commercial and industrial equipment. 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.

Where It Works Best

The HGL36070 makes the most sense in commercial, industrial, and facility electrical distribution applications that specifically require a 70A, three-pole, thermal-magnetic circuit breaker in a PowerPacT H-frame configuration.

It’s particularly useful when the installation calls for a unit-mount breaker with line- and load-side lugs. The AL150HD terminals abide both copper and aluminum conductors from 14 AWG through 3/0 AWG, giving installers flexibility within the specified conductor and torque requirements.
