Specifications

• Amperage rating: 250 A
• Voltage rating: 600 V
• Number of poles: 3
• Type: Thermal-magnetic molded case circuit breaker
• Part number: KDB3250X
• Application: Branch circuit overcurrent and short-circuit protection in panelboards and load centers

Ideal use scenarios

• Upgrading or replacing aging protection devices in residential panels that require a reliable, high-capacity 3-pole breaker.
• Distributing power for commercial spaces with moderate-to-heavy load profiles across 3-phase equipment.
• In light industrial facilities where space constraints demand a compact MCCB without compromising protection quality.
• New installations or panel retrofits that call for compatible Eaton components to maintain system integrity and warranty coverage.

Why this matters

The KDB3250X combines space-efficient design with precise protection. The thermal element handles gradual load changes, while the magnetic mechanism delivers instantaneous disconnect during a short-circuit, reducing damage to wiring and connected equipment. Its compatibility with Eaton OEM panels means fewer integration challenges and consistent performance across your distribution system, helping you minimize downtime and maintenance costs in the long run.

Practical tips

• Verify that your panelboard is compatible with Eaton KDB-series devices and that the 600 V, 250 A rating matches your system requirements.
• Plan for three-phase applications where a true 3-pole breaker is needed to protect all conductors equally.
• Keep a spare KDB3250X on hand for maintenance or future upgrades to reduce panel downtime.
• When replacing an existing breaker, confirm the replacement’s trip characteristics align with your load profile to avoid nuisance trips or under-protection.
