Why choose the KB3175 for your panel

The KB3175 is built to align with Westinghouse engineering standards, delivering dependable protection for three-phase circuits. By relying on the exact part number, you minimize the risk of inexact replacements and ensure the breaker’s trip characteristics and mechanical fit match your panel’s design.

Ideal use cases

• Replacing worn or failed breakers in three-pole, three-phase installations
• Retrofit projects where maintaining original protection schemes is essential
• Stocking a reliable spare for service crews handling Westinghouse or compatible panels

Installation and compatibility notes

Before you order, verify that your panel model aligns with the KB3175 specification. Use the part number as the best compatibility reference and confirm the panel’s current rating and voltage requirements match your system. For safety, have a licensed electrician handle installation and power isolation to prevent accidental energization.

What to expect in practice

With the KB3175, you gain a dependable, three-pole solution designed to support consistent overcurrent protection in appropriate Westinghouse environments. Its 3-pole design enables synchronized protection across three conductors, helping maintain system integrity during fault conditions and simplifying downstream maintenance checks.

Care and handling tips

• Store spares in a dry, vibration-free location to preserve terminal integrity
• Inspect the breaker for any signs of physical damage before installation
• Handle with the main power fully disconnected and follow panel manufacturer guidelines
