Description

These ceramic insulators are designed for use in Westinghouse 2050A15G45 Size 5 arc boxes, with compatibility for Cutler Hammer systems. They serve as critical components in medium-voltage contactors and circuit breakers, providing electrical insulation and arc quenching to prevent damage from electrical arcs during switching operations. Made from high-grade ceramic material, they offer excellent thermal resistance, dielectric strength, and durability in harsh industrial environments such as power distribution, motor control centers, and heavy machinery applications. Advantages include superior arc interruption compared to plastic alternatives, reducing wear on contacts and extending equipment life. Drawbacks may include higher cost and brittleness if mishandled. These insulators are ideal for retrofitting or maintaining legacy Westinghouse and Eaton/Cutler Hammer equipment, ensuring reliable performance in high-current scenarios. Based on image analysis, these appear to be new or unused parts, with no visible wear, cracks, or discoloration. No parent/child assets are evident in the images, but they are typically installed in arc chute assemblies as shown.
