Meltric DS Series 20A Poly Receptacle 33-34143

The Meltric DS Series 20A Poly Receptacle (model 33-34143) is a robust, switch-rated device designed for safe and reliable power connections in industrial environments. Part of Meltric's Decontactor series, it combines the functionality of a plug, receptacle, and disconnect switch into one unit, allowing for safe make-and-break operations under full load without the need for interlocks or auxiliary equipment. Key features include a dead-front safety shutter that prevents access to live parts, silver-nickel butt-style contacts for low resistance and durability, and an IP66/IP67 watertight rating for harsh conditions. It supports up to 600VAC and is ideal for applications in manufacturing, food processing, and temporary power setups where frequent connections/disconnections are required. Advantages over standard plugs include enhanced safety (arc flash reduction), longer lifespan due to spring-loaded contacts, and compliance with NEC requirements for branch circuit disconnects. Drawbacks may include higher initial cost compared to basic connectors and the need for compatible Meltric plugs. Based on image analysis, this unit appears used with minor wear, including handwritten labels like 'CKT 1', but remains functional with no visible damage to critical components.
