Appleton Contender CPS Factory-Sealed 20A Pin and Sleeve Receptacle

The Appleton Contender™ CPS Factory-Sealed Pin and Sleeve Receptacle delivers explosionproof protection for stationary or portable equipment operating in hazardous, damp, or corrosive locations. Rated 20A at 125-250 Vac or 18 Vdc with a 3-pole, 2-wire configuration, this receptacle is built for Class I, Division 1 and 2, Groups C, D hazardous area service and meets all UL and CSA requirements for ground fault protection when used with the GFCI cover. Factory sealing eliminates the need for external seals, simplifying installation in demanding industrial environments.

Key Features

  • Delayed Action Construction: Insert the plug to first stop, move the Slide-Lok™ slide to the right, then push the plug fully forward to energize – a deliberate two-step engagement that reduces arcing risk.
  • Factory Sealed: External seals are not required, streamlining hazardous location installation.
  • Durable Construction: Receptacle cover and CPP516 plug are copperfree (4/10 of 1% max.) aluminum with epoxy powder coat finish; mounting box is malleable iron with triple-coat protection; insulating blocks are fiberglass reinforced polyester for superior dielectric and mechanical strength with lowest arc tracking.
  • Electrical Rating: 20A at 125-250 Vac or 18 Vdc, 3-pole, 2-wire, with a 1 horsepower rating for reliable power delivery.
  • Mounting Box Entries: Available in Dead-End or Feed-Thru configurations to suit installation layout.
  • Strain Relief: Plug mechanical cable clamps prevent strain on cables and meet or exceed UL strain relief pull-out requirements; plug cable diameter range is .538 – .639.

Appleton CPP516 – Frequently Asked Questions

1) Do I need to install an external conduit seal with this Appleton explosionproof receptacle?
No external seal is required. The Contender CPS receptacle is factory sealed, so the seal is built into the assembly and you can wire straight into the box without adding a sealing fitting at the enclosure. That is the main labor saving over a non-sealed hazardous location receptacle.
2) Is this Appleton receptacle GFCI protected on its own?
Ground fault protection comes from the cover, not the receptacle body. The assembly meets UL and CSA requirements for ground fault protection in hazardous locations when used with the GFCI cover, so if your installation requires GFCI you must specify that cover version rather than assuming the receptacle provides it.
3) What cable diameter does the CPP516 plug clamp accept?
The plug cable clamp takes cable from .538 to .639 inches in diameter. The mechanical clamps meet or exceed UL strain relief pull-out requirements, so portable cord feeding equipment is supported at the plug rather than at the terminals. Cord outside that range will not clamp correctly.
4) Can I use a heavy-duty industrial duplex receptacle instead of a pin and sleeve in a classified area?
No. Spec grade and heavy-duty industrial devices like the Bryant 5362B 20A/125V heavy-duty duplex or the Eaton Arrow Hart 15A 125V 5-15R industrial receptacle are for unclassified commercial and industrial spaces. Neither carries the Class I Division 1 and 2, Groups C and D rating the Contender CPS has, and neither is factory sealed. In a classified area you need the explosionproof pin and sleeve device.
5) What is the difference between the Appleton Contender CPP516 and a twist-lock receptacle like the Pass & Seymour Turnlok 3330?
The Appleton Contender CPS CPP516 is a pin and sleeve device with a Slide-Lok delayed-action mechanism: the plug goes in to a first stop, the slide moves right, then the plug pushes fully forward to energize, which is a deliberate two-step engagement that reduces arcing risk, and it is factory sealed for Class I, Division 1 and 2, Groups C, D locations at 20A, 125-250VAC. The Pass & Seymour Turnlok 3330 is a 30A non-NEMA single locking receptacle that retains the plug by rotation and is an ordinary-location device. They are different connector systems and their plugs are not interchangeable.
6) For GFCI protection at a 20A receptacle, is the Appleton Contender CPP516 or the Pass & Seymour 2097HGI the right choice?
It depends on the location. The Appleton Contender CPS CPP516 meets UL and CSA requirements for ground fault protection in hazardous locations when used with the GFCI cover, and is built for Class I, Division 1 and 2, Groups C, D service in damp or corrosive industrial areas. The Pass & Seymour 2097HGI is a hospital grade 20A duplex self-test GFCI receptacle in ivory, intended for patient care and similar interior ordinary-location work. Use the Contender CPS where the area is classified and the 2097HGI where hospital grade duplex GFCI is specified.
7) What voltage and load can this 20A pin and sleeve receptacle handle?
20A at 125 to 250 Vac, or 18 Vdc, in a 3-pole 2-wire configuration with a 1 horsepower rating. The 1 HP rating is what matters if you are feeding a motor load rather than general receptacle loads.
8) How does the Slide-Lok delayed action engagement work on the Contender CPS receptacle?
It is a deliberate two-step connection. You insert the plug to the first stop, slide the Slide-Lok slide to the right, then push the plug fully forward to energize the contacts. Because the circuit does not make until the plug is mechanically captured, arcing risk at insertion and withdrawal is reduced, which is why this construction is used in hazardous areas.
9) Do I order a dead-end or feed-thru box for this pin and sleeve receptacle?
Both mounting box entry configurations exist, so choose by how the circuit runs. Dead-end suits an end-of-run device where the conduit terminates at the receptacle. Feed-thru lets the run continue on to the next device without a separate junction. The box is malleable iron with triple-coat protection either way.
10) Will this hold up in a corrosive or washdown industrial area?
The materials are picked for it. Receptacle cover and plug are copperfree aluminum (4/10 of 1% max copper) with an epoxy powder coat, the mounting box is malleable iron with triple-coat protection, and the insulating blocks are fiberglass reinforced polyester for dielectric strength and low arc tracking. It is rated for damp and corrosive locations as well as hazardous ones.
11) I need a locking receptacle for portable equipment but the area is not hazardous. What else is there?
If there is no area classification to satisfy, a twist-lock device is the simpler route. ZenSupply carries the Bryant 70520FR 7 Series NEMA flanged locking receptacle, the Pass & Seymour Turnlok 30A non-NEMA single receptacle, and the Eaton 50A 600V/250V AC/DC extra heavy duty industrial locking receptacle for larger loads. The Contender CPS is the choice only when Class I Division 1 or 2, Groups C or D coverage is required.
12) Is a flanged locking receptacle such as the Bryant 70520FR a substitute for the Appleton Contender CPP516 on portable equipment?
They serve different environments. The Appleton Contender CPS CPP516 is intended for stationary or portable equipment in hazardous, damp, or corrosive locations, with plug mechanical cable clamps that meet or exceed UL strain relief pull-out requirements and a plug cable diameter range of .538 to .639 inch. The Bryant 70520FR is a 7 Series NEMA flanged locking receptacle for ordinary-location equipment inlets and does not carry explosionproof factory-sealed construction.
13) If I only need a 20A spec grade receptacle in a plant office instead of the Appleton Contender CPP516, what fits?
The Appleton Contender CPS CPP516 is a copperfree aluminum, epoxy powder coat pin and sleeve device meeting UL-CSA standards for classified areas, which is more device than an unclassified interior needs. For ordinary-location 20A work, the Pass & Seymour 26352W is a 20A 125V heavy-duty specification grade decorator duplex receptacle in white. It is a standard wall device and cannot be used where a Class I, Division 1 or 2 receptacle is required.
14) Which plug works with the Appleton Contender CPS receptacle cover, and can a standard industrial plug be used?
The Contender CPS covers are UL Classified for use with the CPP516 plug, whose body is copperfree aluminum with an epoxy powder coat finish and which is supplied with pressure terminal connectors and mechanical cable clamps. Standard ordinary-location cord caps for devices like the Eaton 5262W, a 15A 125V 5-15R industrial duplex receptacle, are a different configuration entirely and will not mate with the pin and sleeve interface.
15) Does the Appleton CPS receptacle come with terminal connectors or do I need to add lugs?
Both the plug and receptacle are supplied with pressure terminal connectors, so wiring is landed directly under the pressure terminals with no separate lugs to buy.
