Killark KP-20ABC SU78 20A 115/230V AC Industrial Pin and Sleeve Plug

The Killark KP-20ABC SU78 is a robust industrial pin and sleeve plug designed for hazardous and demanding environments, manufactured by Killark, a Hubbell company specializing in explosion-proof electrical equipment. This plug is rated for 20A at 115/230V AC, featuring a 2-wire, 3-pole configuration with grounding, making it suitable for applications in industrial settings such as oil and gas, chemical processing, and manufacturing facilities where reliable power connections are critical. Key features include a durable aluminum alloy construction for corrosion resistance, watertight seals, and compatibility with hazardous locations (Class I, Div 1 & 2, Groups B, C, D per UL/CSA certifications visible on the label). Advantages over similar products include superior environmental protection (NEMA 4X rating equivalent), easy installation with cable grip for strain relief, and included accessories like rubber caps for unused ports. Benefits include enhanced safety in volatile atmospheres, reducing risk of sparks or failures, though drawbacks may include higher cost compared to standard plugs and the need for compatible receptacles. This model excels in high-vibration or wet conditions, offering longevity and minimal maintenance. Based on image analysis, the unit appears to be new old stock (NOS) in original packaging, with minor box wear but no visible damage to the plug itself. Applications range from portable equipment powering to fixed installations in refineries.
