• Poles: 3-Pole
• Voltage: 600V
• Part number: KB3250WSK

Notes: Confirm fit and ratings before ordering. The part number KB3250WSK is the best reference for compatibility, ensuring a seamless retrofit or replacement in existing panels.

Why this breaker stands out

This Westinghouse KB3250WSK is purpose-built for maintenance, retrofit, and replacement when matching specifications are essential. It provides consistent tri-phase protection, which is critical for motors, conveyors, and other 3-phase loads. By aligning with the exact 250A, 3-Pole, and 600V spec, you minimize downtime and cabinet modification while preserving accurate protection characteristics.

Practical use cases

• Maintenance: Replace worn or malfunctioning breakers in service panels to restore reliable protection without surprises.
• Retrofit: Upgrade or reconfigure existing 3-phase circuits to a known, compatible spec that matches your panel’s bus arrangement.
• Replacement: Stand-in for legacy breakers in equipment racks and switchgear where the KB3250WSK spec is required.

Installation and compatibility tips

• Always verify fit and ratings against your panel’s documentation before ordering.
• Use the KB3250WSK part number as the primary compatibility reference to avoid mismatches.
• Ensure the panel supports 600V systems and 250A overcurrent protection with a 3-pole configuration.
• Follow all local electrical codes and the manufacturer’s installation guidelines during replacement.
