Eaton EHD2100 - 100 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Introducing the Eaton EHD2100 — a 100A, 480V, 2-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and loadcenters. Built for demanding electrical environments, this breaker blends rugged construction with precise protection to keep electrical systems safe and up and running.

Secure, vibration-resistant bolt-on mounting

Hard-mount your protection where it belongs with a bolt-on design that delivers a rigid bus connection. The secure attachment minimizes movement and loosening due to vibration or equipment start-up, helping maintain consistent electrical contact and reducing nuisance trips.

Thermal-magnetic protection for reliable safety

The thermal-magnetic trip unit provides stable, repeatable protection across varying load and ambient conditions. The thermal element responds to sustained overcurrent, while the magnetic element acts quickly during short-circuit events, delivering fast disconnection to safeguard wiring and connected equipment.

OEM-endorsed compatibility

Specifically engineered to work with matching Eaton OEM loadcenters and panelboards, the EHD2100 ensures coordinated protection and a seamless fit within your existing electrical architecture. This compatibility helps simplify replacements, maintenance, and future panel upgrades.

Ideal applications

• Residential, commercial, and light industrial panels that require robust 2-pole overcurrent protection
• Existing panelboards and loadcenters where bolt-on breakers are preferred for a secure, long-lasting connection
• Systems where 480V operation is standard and reliable 100A protection is needed for branch circuits
