Sylvania Type PM Slim Jim Relay KPMA-1 / KPMF-1

The Sylvania Type PM Slim Jim Relay, models KPMA-1 and KPMF-1, is a compact, versatile power relay designed for industrial control applications. Part of the Bulletin 7303 series, these relays are known for their slim profile, making them ideal for space-constrained panels in manufacturing, automation, and electrical distribution systems. They feature robust construction with screw terminals for secure connections and are suitable for switching high-power loads in AC circuits. Key benefits include reliable performance in demanding environments, easy installation, and compatibility with legacy systems from Clark or Sylvania-era equipment. Drawbacks may include limited availability of parts due to the product's vintage status (likely from the 1970s-1980s) and potential need for refurbishment in used units. Compared to modern relays like those from Siemens (which acquired Sylvania's electrical division), the Slim Jim offers cost-effective retrofitting for older setups but lacks advanced features like digital interfaces or higher efficiency ratings. Applications include motor control, lighting systems, and HVAC equipment. Based on image analysis, these units appear used with visible wear but intact components, including faceplates showing catalog numbers and voltage ratings. No parent/child assets are evident in the images.
