Eaton EDH3100 - 100 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Eaton EDH3100 is a 100 A, 240 V, 3-pole bolt-on molded case circuit breaker designed to protect branch circuits and guard against short circuits in panelboards and loadcenters. Built for reliability, it offers a secure mounting and precise protection you can count on in residential, commercial, and light industrial settings.

Secure, vibration-resistant mounting

With a bolt-on mounting style, the EDH3100 creates a rigid, vibration-resistant bus connection that stays tight through equipment cycling, temperature changes, and panel enclosures that experience movement. This stability translates to consistent tripping behavior and reduced maintenance over time.

Thermal-magnetic protection for dependable trip response

The thermal-magnetic trip unit delivers stable, repeatable protection. It responds to sustained overcurrent with thermal elements and to short circuits with magnetic elements, helping protect conductors and connected equipment from damage.

Designed for compatibility and simple upgrades

Designed to be compatible with matching OEM load centers and panelboards, EDH3100 ensures straightforward installation when you’re replacing an older breaker or expanding a panel. Its 3-pole configuration is ideal for 240 V circuits that require synchronized switching and balanced phasing.

Ideal for a wide range of applications

Whether you’re wiring a new home electrical panel, retrofitting a small commercial panel, or equipping a light industrial distribution board, the EDH3100 provides reliable overcurrent and short-circuit protection. Use cases include feeders to outlets, lighting circuits, and essential equipment feeders where robust protection is essential.
