Square D HDL26050 Molded Case Circuit Breaker 50A 2 Pole

Product Description

The SQUARE D HDL26050 is a 2-pole, molded case circuit breaker rated for 50 amps, 600 VAC, and 250 VDC. It uses a thermal-magnetic trip mechanism to provide overcurrent and short-circuit protection in panel-mount electrical distribution systems. The breaker accepts wire sizes from 14 AWG through 3/0 AWG via lug-style terminal connections, making it suitable for a wide range of feeder and branch circuit applications. It carries multiple breaking capacity ratings and is listed or certified to UL, CE, CSA, and IEC standards. Licensed electricians install this breaker in commercial, industrial, and heavy residential panels where reliable overcurrent protection is required.

The HDL26050 is used in panel-mount applications across commercial and industrial settings where 2-pole branch or feeder circuit protection is needed at up to 600 VAC or 250 VDC. The lug terminal design accommodates larger conductor sizes, making it appropriate for motor loads, HVAC equipment feeds, and general distribution panels. Its thermal-magnetic trip mechanism responds to both sustained overloads and instantaneous fault currents, covering the full range of typical protective functions expected in a molded case breaker of this class.

Key Features

• 50-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 single-phase 240-volt or DC circuits
• Lug terminal connections accept 14 AWG through 3/0 AWG conductors
• Multiple breaking capacity ratings for flexible application fit
• Certified to UL, CE, CSA, and IEC standards

Compatibility

Designed as an OEM-style panel-mount molded case circuit breaker for commercial and industrial distribution panels requiring 2-pole, 50-amp overcurrent protection at 600 VAC or 250 VDC.

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 lockout/tagout the panel before installing or replacing this breaker. Verify that conductor size and insulation rating are compatible with the lug terminals before torquing connections. Do not exceed the breaker ampere or voltage ratings for the intended circuit.
