Meltric 33-18143 DS20 Male Inlet, 600V AC, 20 Amps
DS20 male inlet rated for 600V AC and 20 Amps, 3 Pole + Ground configuration, 14-8 AWG wiring capacity, fiberglass-reinforced thermoplastic body, Type 3R, IP 54.
Why Choose the Meltric 33-18143 DS20 Male Inlet?
The Meltric 33-18143 DS20 male inlet is built for industrial DS Series power connections where a compact, durable inlet is required. It is rated for 600V AC and 20 Amps and uses a 3 pole + ground with 14-8 AWG wiring capacity.
Its impact-resistant blue thermoplastic polyester body is reinforced with fiberglass to help withstand chemical exposure, UV radiation, and daily plant-floor use. Silver-nickel contacts support reliable conductivity during repeated connecting and disconnecting, while the DS Series design helps reduce arc-flash risk when used with the correct mating device.
