MELTRIC DSN20 Inlet - 20A 277/480V 3P+N+G Industrial Plug/Inlet (63-18047)
The MELTRIC DSN20 Inlet (MPN: 63-18047) is an industrial-grade electrical inlet designed for robust and reliable power connections in demanding environments. As a part of the MELTRIC DS/DSN series, this 20-amp, 277/480V AC device features a 3-pole + neutral + ground (3P+N+G) contact configuration, making it suitable for a wide range of industrial applications, including those requiring horsepower up to 7.5 HP.
This DSN20 inlet is switch-rated, functioning as both a branch circuit disconnect switch and a motor circuit disconnect switch, ensuring safe and compliant power control. Constructed from durable POLY (polymer) material in a distinct blue color, it boasts exceptional environmental protection with Type 4X, IP66/67, and IP69 ratings, signifying superior resistance to water, dust, and even high-pressure washdowns. Its robust build is further evidenced by an IK09 impact rating and a high 100 kA Short Circuit Current Rating (SCCR) for close & withstand, providing maximum safety and reliability (when protected by specific fuse types, e.g., 35A RK1 for 100kA @ 600VAC).
Designed for ease of installation and maintenance, the DSN20 features screw terminals accommodating 14 AWG – 12 AWG wiring. It operates reliably across a broad temperature range from -40°F (-40°C) to 140°F (60°C). MELTRIC's patented keying system ensures that only plugs and receptacles with compatible contact configurations and electrical ratings can mate, preventing accidental misconnections. Additionally, all DSN plugs are equipped with lockout provisions for enhanced safety during maintenance. This inlet is compliant with major standards including UL 1682, UL 2682, cCSAus, and C22.2 No. 182.1-13.
