Eaton EHD1100L - 160 A, 277 V, 1-Pole Circuit Breaker | AmpState

Eaton EHD1100L is a 160A, 277V, 1-Pole molded case circuit breaker engineered for reliable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters.

Designed with a compact molded case, the EHD1100L maximizes usable panel space without sacrificing protection or ease of replacement. Its thermal-magnetic trip unit delivers stable, repeatable protection across varying ambient temperatures and load conditions, reducing nuisance trips and helping keep critical commercial circuits—such as 277V lighting and general power feeds—operational when you need them most.

Key Benefits

• Efficient panel utilization: A compact molded case fits neatly into crowded panelboards, leaving room for future expansion.
• Stable protection with thermal-magnetic trip: Combines thermal and magnetic sensing to respond accurately to both gradual overcurrent and instantaneous short circuits.
• OEM compatibility: Specifically designed to be compatible with matching Eaton OEM loadcenters and panelboards for seamless replacement or upgrades.
• Versatile application range: Suitable for residential, commercial, and light industrial environments where 277V circuits are prevalent.

Ideal Use Cases

• Upgrading or expanding panelboards in office buildings, retail spaces, and other commercial settings that rely on 277V lighting circuits and general power distribution.
• Replacing aging or failed breakers within existing Eaton-installed panel systems to restore reliable protection without reconfiguring wiring.
• New installations where a single-pole, heavy-ampacity protection device is required for dedicated branch circuits.
