Eaton HFD1020L (277 V) - 20 A, 277 V, 1-Pole Circuit Breaker | AmpState

The Eaton HFD1020L (277 V) is a 20A, 1-pole molded case circuit breaker engineered for reliable branch-circuit protection in panelboards and load centers.

Designed for compact spaces, the molded case architecture frees up panel space while delivering precise overcurrent and short-circuit protection. The thermal-magnetic trip unit combines a stable thermal trip with a fast magnetic trip for predictable response—minimizing nuisance trips while guarding equipment, wiring, and occupants.

Key benefits include:

• Compact molded-case design that maximizes panel density and simplifies wiring layouts
• Thermal-magnetic trip unit offering repeatable protection performance across temperature variations
• 277V single-pole configuration ideal for commercial lighting, convenience circuits, and other 277V branch circuits
• 20A current rating provides robust protection for standard-sized branch circuits
• Designed to integrate with matching OEM Eaton panelboards and load centers for a seamless, code-compliant installation
• Suitable for residential, commercial, and light industrial applications where reliable 277V protection is needed

Who benefits most

This breaker is a practical choice for electrical contractors, facility managers, and maintenance teams who work with 277V lighting systems and small power circuits in commercial buildings, schools, retail spaces, and light industrial facilities. It helps simplify procurement by staying within the same Eaton ecosystem, reducing compatibility concerns and stocking complexity.

Key specifications
