Eaton JD3250K - 250 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton JD3250K is a rugged 3-pole, 250 A, 600 V bolt-on molded case circuit breaker engineered for dependable branch circuit protection in panelboards and loadcenters. Built for reliability in residential, commercial, and light industrial environments, it delivers precise protection where it matters most and fits seamlessly into Eaton’s OEM panel ecosystems.

Why the JD3250K stands out

What sets this breaker apart is its combination of secure mounting, precise protection, and OEM compatibility. The bolt-on mounting creates a rigid, vibration-resistant bus connection that stays tight through electrical and environmental stress, helping to prevent loose connections that can lead to nuisance trips or degraded protection.

Key protection you can trust

Equipped with a thermal-magnetic trip unit, the JD3250K provides two layers of safety: the thermal element responds to overload conditions for stable, repeatable protection, while the magnetic element delivers instantaneous response to short circuits. This dual-action protection helps safeguard connected equipment and maintains system uptime even under demanding fault conditions.

Designed for seamless OEM integration

Compatibility with matching Eaton OEM loadcenters and panelboards means straightforward installation, reliable interoperability, and consistent performance across Eaton’s family of enclosure products. No guesswork, just a fit that you can count on in new builds or panelboard upgrades.

Ideal use cases

Whether you’re wiring a residential service, a commercial distribution panel, or a light industrial feeder system, the JD3250K provides robust three-phase protection for main distribution or branch circuits. It’s particularly well-suited for installations where vibration resistance and secure bus connections matter for long-term reliability.
