Square D HDL26070 Molded Case Circuit Breaker 70A 2 Pole

Product Description

The SQUARE D HDL26070 is a 2-pole molded case circuit breaker rated for 70 amps, 600 VAC, and 250 VDC. It uses a thermal-magnetic trip mechanism to provide overload and short-circuit protection in panel-mount installations. Lug-style terminals accept wire from 14 to 3/0 AWG, covering a wide range of conductor sizes. The HDL26070 carries multiple breaking capacity ratings and meets CE, CSA, IEC, and UL Listed standards. Licensed electricians install this breaker in commercial and industrial distribution panels where robust overcurrent protection and compliance with recognized standards are required.

The HDL26070 is suited for commercial and industrial electrical distribution systems requiring a 2-pole, 70-amp molded case circuit breaker at 600 VAC or 250 VDC. It is typically installed in panelboards and switchboards where panel-mount configuration is specified. The wide wire range of 14 to 3/0 AWG allows flexibility in feeder and branch circuit wiring. This breaker fits applications where thermal-magnetic trip characteristics are required for motor feeder, lighting, or general-purpose branch circuit protection.

Key Features

• 70-amp continuous rating with thermal-magnetic trip for overload and short-circuit protection
• Dual voltage rating: 600 VAC and 250 VDC
• 2-pole configuration for 240-volt or DC branch circuit protection
• Lug terminals accept 14 to 3/0 AWG conductors
• Panel-mount design for standard switchboard and panelboard installation
• Certified to CE, CSA, IEC, and UL Listed standards with multiple breaking capacity ratings

Compatibility

Designed as an OEM-style replacement molded case circuit breaker for commercial and industrial panelboard and switchboard applications requiring a 2-pole, 70-amp, 600 VAC panel-mount breaker.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panel before installing or replacing the breaker. Verify that conductor sizing and lug torque meet NEC Table 310 requirements for the installed wire gauge. Do not exceed the breaker amperage, voltage, or interrupting ratings for the intended circuit.
