Eaton KD3250 - 250 A, 600 V, 3-Pole Circuit Breaker | AmpState

Eaton KD3250 is a 3-pole molded case circuit breaker rated at 250A and 600V, built to deliver reliable branch-circuit overcurrent and short‑circuit protection in panelboards and loadcenters.

With a compact molded-case design, the KD3250 helps you maximize panel space without sacrificing protective performance. The thermal-magnetic trip unit provides stable, repeatable protection, instantly responding to overloads and short circuits to shield wiring and connected equipment.

Why choose KD3250 for your electrical distribution

• Space-efficient MCCB design: smaller footprint for tighter panel layouts and easier wiring in residential, commercial, and light industrial installations.
• Reliable protection: thermal-magnetic trip combines instantaneous short‑circuit protection with time-delayed overload protection for coordinated, predictable trips.
• OEM-compatible: designed to be compatible with matching OEM loadcenters and panelboards, ensuring straightforward installation and dependable fit.
• Three-pole, 600V operation: suitable for 3‑phase systems and higher voltage distribution common in commercial and light industrial settings.

Use cases and scenarios

Ideal for new builds or panelboard upgrades where a robust, space-saving 3-pole breaker is required. Use KD3250 to protect feeder circuits, main lugs, or branch circuits in service panels, data centers, or light manufacturing environments. When you need reliable short-circuit interruption at 600V and a 250A rating, this unit is designed to drop in where a KD-series MCCB is specified.
