Meltric DSN20 Switch-Rated Receptacle Selector: Match Voltage, Amperage & Pole Configuration Switch-Rated Selector
Switch-Rated Receptacle Selector: Meltric DSN20 20A GuideLooking for a switch-rated simplex receptacle? Every Meltric DSN20 is a single-outlet 20A switch-rated receptacle. Filter by voltage, pole configuration, and washdown rating to land on the exact part number for your circuit. Switch-Rated DisconnectBreak load safely, no separate disconnect switch needed.
Arc-Flash SafeEnclosed contacts and dead-front design keep the operator clear of the arc.
Washdown ReadyType 4X with IP66/67 or IP69 bodies survive high-pressure hosedown.
100kA WithstandClose-and-withstand short-circuit rating for hard industrial branch circuits.
Quick answer Pick a DSN20 receptacle by matching three things: circuit voltage, pole/neutral configuration, and washdown rating. All DSN20 parts are 20A, switch-rated for load disconnect, 100kA-rated, and take 14-12 AWG. Add the -K16 suffix when you need Type 4X, IP69 high-pressure washdown instead of standard IP66/67. Find the Right ProductAnswer these three and we'll narrow the DSN20 lineup to your part. 1. What is your circuit voltage?
2. How many poles plus neutral/ground do you land?
3. What washdown rating do you need?
All OptionsAll 14 variants share the same 20A rating, 14-12 AWG screw terminals, -40°F to 140°F range, 100kA rating, and 2.2" x 3.03" x 3.15" body. You're choosing voltage, pole/neutral layout, and enclosure rating. Meltric 63-14075 DSN20 20A, 125V, 1P+N+G Female Receptacle

Which One Should You Buy?Find the row that matches your setup:
How These Options DifferStart with your circuit voltage and how many current-carrying poles you actually land. Single-phase line-to-neutral loads (120V/125V/277V) take a 1P+N+G unit like the 63-14125-K16, 63-14075, or 63-14045. Two-hot ungrounded loads (208V, 250V, 480V, 600V) use 2P+G: the 63-14122-K16, 63-14072, 63-14042, and 63-14142. Three-phase, three-wire motors use 3P+G (63-14123-K16, 63-14073, 63-14043). When the load needs both full phases and a neutral (120/208V, 125/250V, or 277/480V), pick the combined-voltage parts: 63-14076, 63-14126-K16, 63-14127-K16, or 63-14047. Then decide enclosure grade: standard parts are Type 4X, IP66/67; the -K16 suffix upgrades to Type 4X, IP69 for direct high-pressure, high-temperature washdown. Note that not all parts have a horsepower rating. The 63-14043 lists 7.5 hp and the 63-14142 (600V) lists 3 hp. Match the exact voltage stamp; do not substitute 250V for 277V or 480V for 600V, which voids the UL/CSA listing. How a switch-rated (Decontactor) receptacle worksA standard receptacle is not rated to break load; pulling a plug under current draws an arc. The Meltric DSN20 is built as a switch-rated disconnect: its contacts open inside the housing before the plug fully separates, so the load is interrupted safely and the operator never sees the arc.
That means one device does the job of a receptacle plus a disconnect switch. It's why several DSN20 units carry horsepower ratings (up to 7.5 hp on the 480V 3P+G 63-14043) and can serve as the motor disconnect at the point of use. How to match DSN20 voltage and pole configurationTwo independent choices drive the part number: voltage and polarity. Get both right and the rest of the DSN20 spec is identical across the line.
Count the current-carrying conductors your load actually lands. A three-phase motor with no neutral needs 3P+G, not 3P+N+G. A 120/208V panel feeding both single- and three-phase loads through the neutral needs a P+N+G part. Never buy on voltage alone: the 250V line has 1P, 2P, and 3P variants. DSN20 vs DSN30 and DSN60: picking the amp versionThis article discusses the 20A version. Size the receptacle to your overcurrent protective device and full-load current, not the other way around.
If your breaker is 20A, the DSN20 is correct and its 14-12 AWG terminals match your conductors. If you're on a 30A or 60A circuit, do not force larger conductors into a DSN20; move up to the DSN30 or DSN60 version, which accepts the appropriate wire range. Voltage and pole logic carries across all three versions, so once you know your voltage and polarity you can select the same configuration in the correct amp size. Choosing between IP66/67 and IP69 (-K16) washdownEvery DSN20 is Type 4X: corrosion-resistant, watertight, UV- and chemical-resistant blue fiberglass-reinforced polyester. The enclosure grade differs by suffix.
For food, beverage, pharma, and sanitary lines that get direct high-pressure/high-temperature hosedown, specify the -K16 version: 63-14125-K16, 63-14122-K16, 63-14123-K16, 63-14126-K16, or 63-14127-K16. For general wet or outdoor industrial use, the standard IP66/67 parts are sufficient. The 600V 63-14142 also carries an IK08 impact rating for mechanical abuse. Both grades share the same footprint and terminals, so the choice is purely about the wash environment. DSN20 configurations at a glance (all 20A, 14-12 AWG, 100kA, -40°F to 140°F)
Common Mistakes (and the Fix)✗ Buying on voltage alone and ignoring pole count ✓ The 250V line has 1P, 2P, and 3P versions. Confirm how many phases and whether you land a neutral before ordering. ✗ Substituting a 480V unit on a 600V circuit ✓ Match the exact voltage stamp; use the 600V 63-14142 for 600V loads. Over-voltaging voids the UL/CSA listing. ✗ Treating it like an ordinary receptacle ✓ It's switch-rated, you can break load with it, but install it per its disconnect application, not as a general convenience outlet. ✗ Specifying standard IP66/67 for direct high-pressure washdown ✓ Use the -K16 IP69 parts anywhere sanitary hosedown with high-temperature jets occurs. ✗ Forgetting the mating plug and housing ✓ Order the matching DSN20 plug and angle adapter or handle/housing in the same voltage and pole configuration to complete the connection. ✗ Forcing oversized conductors into a DSN20 ✓ DSN20 accepts 14-12 AWG only; for 30A/60A circuits move up to the DSN30 or DSN60 frame. Frequently Asked QuestionsWhat does DSN20 mean on a Meltric receptacle?DSN is Meltric's Decontactor switch-rated series and 20 is the amp rating, so every DSN20 is a 20A device. You then choose voltage and pole configuration. All DSN20 bodies here share the same 2.2" x 3.03" x 3.15" footprint and 14-12 AWG screw terminals. Is a DSN20 a simplex receptacle?Yes, it's a single-outlet (simplex) industrial receptacle, but with a critical difference: it's switch-rated for branch-circuit and motor-circuit disconnect switching. Unlike a standard simplex receptacle, you can make and break load at full current under a 100kA short-circuit rating without arc-flash exposure to the operator. How is DSN20 different from DSN30 or DSN60?The number is the amp rating: DSN20 = 20A, DSN30 = 30A, DSN60 = 60A. If your overcurrent device and load exceed 20A, step up to DSN30 or DSN60. Pole/neutral configuration and voltage selection follow the same logic across all three frames. This page covers the 20A frame only. What does the -K16 suffix mean?The -K16 parts (like 63-14125-K16 and 63-14123-K16) carry a Type 4X, IP69 rating, meaning total dust protection and resistance to high-pressure, high-temperature water jets from any direction. Non-K16 parts are Type 4X, IP66/67. Choose -K16 for direct sanitary washdown. Can I use a 250V DSN20 on a 277V circuit?No. Match the exact voltage stamp. A 250V unit (63-14072) is not rated for 277V; use the 277V part (63-14045). Likewise the 480V parts (63-14042/63-14043) are not a substitute for 600V (63-14142). Over-voltaging voids the UL/CSA listing and is a safety hazard. Do I need the receptacle and the plug, or just this?This article covers the female receptacles only. A complete Meltric connection also needs the mating DSN20 plug and, typically, an angle adapter or handle/housing. Match the plug's voltage and pole configuration to the receptacle you pick here. What wire size do DSN20 receptacles accept?All DSN20 variants take 14-12 AWG on screw terminals, rated -40°F to 140°F (-40°C to 60°C). That covers standard 20A branch-circuit conductors. Torque terminals to Meltric's published spec and confirm your conductor insulation temperature rating. Can a DSN20 serve as a motor disconnect?Yes. DSN20 units are rated for branch-circuit and motor-circuit disconnect switching, and the parts with a published horsepower rating can serve as the motor disconnect at the point of use. For example, the 63-14043 lists 7.5 hp at 480V. Confirm your motor's full-load current and HP fall within the specific part's listed rating. Terms Worth Knowing
