Square D HDL26020 Molded Case Circuit Breaker 20A 2P

Product Description

The SQUARE D HDL26020 is a 2-pole, molded case circuit breaker rated for 20 amps at 600 VAC and 250 VDC. It uses a thermal-magnetic trip mechanism to provide reliable overload and short-circuit protection in panel mount installations. The breaker accepts wire sizes from 14 AWG to 3/0 AWG via lug-type terminals, making it suitable for a wide range of conductor sizes encountered in commercial and industrial electrical systems. Electricians and electrical contractors install this breaker as a branch-circuit or feeder protective device where high-voltage DC or AC distribution is required. It carries CE, CSA, IEC, and UL Listed certifications, confirming it meets multiple international and North American safety standards.

The HDL26020 is suited for panel mount applications in commercial, industrial, and heavy-duty residential electrical distribution systems. It fits into loadcenters and distribution panels where a 2-pole, 20-amp molded case circuit breaker is specified. The thermal-magnetic trip design responds to both sustained overload conditions and instantaneous fault currents, making it appropriate for motor branch circuits, feeder protection, and general-purpose branch circuit applications where 600 VAC or 250 VDC ratings are required.

Key Features

• 20-amp continuous rating at 600 VAC and 250 VDC
• 2-pole configuration for single-phase 240-volt or DC circuit protection
• Thermal-magnetic trip mechanism provides overload and short-circuit protection
• Lug terminal connection accepts 14 AWG to 3/0 AWG conductors
• Panel mount design for standard distribution panel installation
• CE, CSA, IEC, and UL Listed certifications for broad compliance

Compatibility

Designed as an OEM-style replacement or new-installation molded case circuit breaker for commercial and industrial panel mount distribution applications requiring a 2-pole, 20-amp, 600 VAC rated breaker.

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 removing or installing the breaker. Verify conductor sizing and lug torque requirements per the manufacturer labeling on the breaker body before terminating wires. Do not exceed the rated voltage or amperage for the circuit being protected.
