Square D HDA36080 Molded Case Circuit Breaker 80A 600V

Product Description

The SQUARE D HDA36080 is a 3-pole, plug-in molded case circuit breaker rated for 80 amps at 600 VAC. It uses a thermal-magnetic trip mechanism to provide overcurrent and short-circuit protection in commercial and industrial power distribution systems. The breaker accepts I-Line and lug terminal connections, giving installers flexibility in panelboard applications. Wire range is 14 AWG through 3/0 AWG, covering a wide range of conductor sizes common in commercial branch and feeder circuits. Licensed electricians install this type of device as part of listed electrical distribution equipment in accordance with NEC requirements.

The HDA36080 is suited for use in commercial and light industrial power distribution panelboards where 3-pole, 80-amp branch or feeder circuit protection is required. Its plug-in mounting style allows for straightforward installation into compatible I-Line panelboard interiors. The multiple breaking capacity ratings make it adaptable across a range of fault-current environments without requiring a separate current-limiting device in lower available fault-current installations.

Key Features

• 80-amp continuous rating at 600 VAC across 3 poles
• Thermal-magnetic trip mechanism for overcurrent and short-circuit protection
• Plug-in mount with I-Line and lug terminal connection options
• Wire range: 14 AWG to 3/0 AWG
• Multiple breaking capacity ratings for use across varied fault-current environments

Compatibility

Designed as an OEM-style replacement molded case circuit breaker for compatible I-Line panelboard interiors rated for plug-in 3-pole devices.

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 panelboard before installing or removing the breaker. Verify that the panelboard bus is rated for the plug-in connection style and that the available fault current at the installation point does not exceed the breaker breaking capacity rating. Do not modify the breaker terminals or alter the factory trip calibration.
