Eaton EHD1030L - 30 A, 277 V, 1-Pole Circuit Breaker | AmpState

Eaton EHD1030L is a 30A, 277V, 1-pole molded case circuit breaker designed to deliver reliable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. Its compact molded-case footprint frees valuable panel space while maintaining robust protection for commercial, residential, and light industrial electrical systems.

Why this breaker stands out

• Compact molded-case design maximizes panel occupancy efficiency, letting you fit more circuits in the same enclosure without sacrificing protection.
• Thermal-magnetic trip unit provides stable, repeatable protection with fast response to short-circuit events, reducing the risk of damage to wiring and connected equipment.
• 277V, 1-pole, 30A specification tailored for lighting and power circuits common in commercial environments, as well as select residential applications.
• OEM compatibility designed to pair seamlessly with matching Eaton OEM load centers and panelboards for straightforward replacement or upgrade projects.
• Versatile application range suitable for residential subpanels, commercial electrical rooms, and light industrial installations where dependable circuit protection matters most.

Who should consider the Eaton EHD1030L

Ideal for electrical technicians and facilities managers looking to upgrade or stock essentials for 277V circuits. Use it in panelboards and load centers where a single-pole, 30A protection device is required—especially in commercial lighting layouts or equipment feeds that operate at 277V. It’s a practical choice when space efficiency, reliable protection, and OEM compatibility are priorities.

What problems it solves

• Prevents nuisance trips on normal load due to stable thermal-magnetic operation, while still delivering instantaneous response to short circuits.
• Maximizes panel real estate with a compact form factor, helping you design cleaner, more accessible electrical spaces.
• Streamlines maintenance and replacements by matching Eaton load centers and panelboards, reducing compatibility concerns.
