Eaton EHD3090L is built to deliver dependable, precise protection for your electrical distribution. As a 90A, 480V, 3-pole molded case circuit breaker, it fits seamlessly into panelboards and load centers, offering reliable overcurrent and short-circuit protection where it matters most. Why this breaker stands out
- Space-efficient, molded case design: The compact footprint helps you maximize panel real estate, making room for essential feeders and future expansions without sacrificing protection.
- Robust thermal-magnetic trip system: The combination of thermal overload and magnetic short-circuit sensing provides stable, repeatable protection across varying load conditions, reducing nuisance trips while safeguarding downstream devices.
- Exact fit with OEM panels: Designed to pair with matching OEM loadcenters and panelboards, ensuring proper electrical coordination, mounting, and field reliability.
- Versatile for multiple environments: Suitable for residential, commercial, and light industrial applications where reliable 90A protection at 480V is needed—think subpanels for small offices, retail spaces, or equipment circuits in light industrial settings. What problems it solves
- Prevents damage from overcurrent and short circuits by interrupting fault current quickly and predictably, helping protect wiring, transformers, and connected equipment.
- Reduces downtime from unpredictable trips by delivering consistent protection behavior through a trusted thermal-magnetic mechanism.
- Enables efficient panel design by offering a compact, compatible 3-pole solution that coordinates with existing OEM components. Ideal use scenarios
- Subpanels in small to mid-sized commercial builds where space is at a premium but protection is non-negotiable.
- Main distribution applications in residential or light commercial setups requiring 90A at 480V and clean phase balancing.
- Equipment feeds and distribution circuits in warehouses or light manufacturing facilities where both overload and short-circuit protection are critical. Technical snapshot
