What makes the KA3125 3-Pole a smart choice

• Three-pole design for comprehensive protection. Suitable for 3-phase applications or circuits that require simultaneous disconnect across all conductors, ensuring coordinated shutoff and reduced risk of arc faults.
• Definitive reference for compatibility. The KA3125 part number is the best reference when matching breakers to Westinghouse panels and enclosures, streamlining ordering and installation.
• Built for real-world retrofit and replacement. Ideal when upgrading aging panels, restoring functionality after a fault, or refreshing a downtime-prone distribution path.
• Clear fit-and-rating guidance. Notes emphasize confirming the fit and ratings before ordering, helping you avoid mismatches and unexpected downtime.

Who benefits most

• Electrical technicians and maintenance teams maintaining Westinghouse panel boards in commercial facilities, factories, schools, or healthcare environments.
• Facilities managers conducting planned upgrades or emergency replacements where a precise 3-pole device is required.
• Installers seeking a reliable, manufacturer-matched component to minimize compatibility issues and installation time.

Compatibility and how to buy

Before purchasing, cross-check the exact KA3125 model with your panel labeling and service requirements. The part number is the most reliable reference for ensuring a proper fit, electrical rating, and mounting footprint. If your documentation lists KA3125, you’re aligned with Westinghouse’s original design intent and performance expectations.

Installation and practical considerations

For safe, effective installation, power down the circuit and follow standard lockout/tagout procedures. Use the KA3125 only in panels and enclosures designed to accommodate a 3-pole Westinghouse breaker of this model. Keep in mind that proper torque on mounting screws and correct bus bar alignment are essential for a secure connection and reliable tripping behavior. If you’re unsure about compatibility, consult the equipment’s installation guide or a licensed electrician.
