Square D HDL26020 – PowerPact™ H-Frame Molded Case Circuit Breaker
The Square D HDL26020 by Schneider Electric is a 2-pole, 20-amp, 600V thermal magnetic molded case circuit breaker built for demanding industrial and commercial electrical systems. Part of the trusted PowerPact H-Frame series, it delivers reliable overload and short-circuit protection with a standard interrupting capacity of 14 kA at 600VAC and 18 kA at 480VAC.
Engineered for unit-mount panelboard installations, this breaker features feed-thru (line and load side lug) terminals, making it suitable for both standard and reverse-fed applications. It is UL 489 Listed and compliant with CSA, IEC 60947-2, NOM, and CE standards — ensuring it meets the requirements of a wide range of industrial projects.
Key Features
- ✅ Thermal Magnetic Trip Protection – Long-time (overload) and instantaneous (short-circuit) trip functions
- ✅ Dual-Break Rotating Contacts – Reduces peak current during short-circuit faults for enhanced equipment protection
- ✅ Integral Push-to-Trip Button – Allows manual tripping directly from the breaker cover for maintenance and testing
- ✅ Feed-Thru Terminal Style – Line and load side lugs included; suitable for reverse-fed applications
- ✅ Non-Interchangeable Trip Unit – Factory-set for consistent, reliable performance
- ✅ H-Frame, Unit Mount Design – Designed for integration into Square D PowerPact panelboards and switchboards
