Square D HDL26080 Molded Case Circuit Breaker 80A 2 Pole

Product Description

The SQUARE D HDL26080 is a 2-pole molded case circuit breaker rated for 80 amps, 600 VAC, and 250 VDC. It uses a thermal-magnetic tripping mechanism that provides both overload and short-circuit protection in a single device. The breaker accepts wire sizes from 14 to 3/0 AWG via lug-style terminal connections and mounts directly to a panel. It 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 reliable overcurrent protection is required for branch circuits or feeder applications.

This breaker is suited for panel-mount installations in commercial, industrial, and heavy-duty residential electrical systems. The 600 VAC rating makes it appropriate for use in three-phase and single-phase distribution equipment. Its wide wire range of 14 to 3/0 AWG accommodates a broad range of conductor sizes, reducing the need for reducers or adapters at the lug terminations. The 250 VDC rating also allows deployment in DC bus or battery-backed systems where DC overcurrent protection is required.

Key Features

• 80-amp continuous current rating with thermal-magnetic trip for overload and short-circuit protection
• Dual voltage rating: 600 VAC and 250 VDC for AC and DC applications
• 2-pole configuration for single-phase or DC circuit protection
• Lug terminal connections accept 14 to 3/0 AWG wire
• Panel-mount design for direct installation in distribution enclosures
• Multiple breaking capacity ratings; certified to CE, CSA, IEC, and UL standards

Compatibility

Designed as an OEM-style replacement molded case circuit breaker for panel-mount applications requiring a 2-pole, 80-amp, 600 VAC thermal-magnetic breaker with lug terminals.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel before installing or replacing the breaker. Verify that conductor ampacity and wire size are compatible with the 14 to 3/0 AWG lug range before terminating. Do not exceed the published voltage or amperage ratings for the circuit being protected.
