Appleton ECS175 U-Line Factory Sealed Plug and Receptacle

The Appleton ECS175 U-Line Factory Sealed Plug and Receptacle line covers 15 and 20 Amp plugs and receptacles built with a dead-front design for use with electrical equipment in hazardous locations. Rated 125 Vac or 250 Vac with 1 and 2 horsepower ratings, this U-Line ECS Series is factory sealed, so external seals are not required and arcing stays safely confined to the receptacle interior. A neoprene gasket in the throat of the receptacle seals against the plug or the spring-loaded cover to keep out water, dust, and corrosive compounds.

Key Features

  • Amperage: 15 and 20 Amp rated for reliable circuit connection.
  • Voltage: 125 Vac or 250 Vac operation.
  • Durable Construction: Receptacle, cover, mounting box, connector housings, caps, and ECP plug are copper-free (4/10 of 1% max.) aluminum with epoxy powder coat for corrosion resistance.
  • Insulating Blocks: Fiberglass reinforced polyester insulating blocks provide superior dielectric and mechanical strength with the lowest arc tracking.
  • Factory Sealed Design: No external seals required; arcing is safely confined to the receptacle interior.
  • Blade-Type Brass Contacts: Unique blade-type brass contacts exert constant pressure along the entire contact surface for superior electrical contact.
  • Horsepower Ratings: 1 and 2 HP.
  • Number of Poles: 3, with 2 wires, for grounded connections.

Certifications & Compliance

  • Class I, Division 1 and 2, Groups B, C, D
  • Class II, Division 1 and 2, Group G (Coal Dust)

Why Appleton?

Appleton engineers the U-Line ECS Series with copper-free aluminum housings, epoxy powder coat finishing, and fiberglass reinforced polyester insulating blocks so plugs and receptacles hold up to the demands of Class I, II, and III hazardous locations. The factory-sealed, dead-front design and blade-type brass contacts deliver dependable, code-compliant performance that electrical professionals can rely on in the toughest industrial environments.

U-Line family note: ECS175 is the base 15/20A ECS-series factory-sealed device; the ECSK-2023 listing is the packaged 3-pole SET built around the same ECS mechanism. Both are the dead-front ECS design, a different mechanism from the EFSR/straight-blade line and the Contender sub-line (separate listings).

Appleton ECS175 – Frequently Asked Questions

1) Do I need to install a conduit seal near the Appleton ECS175 receptacle?
No external seal is required. The ECS175 U-Line receptacle is factory sealed, so any arcing stays confined inside the receptacle interior and you do not have to add a sealing fitting at the device. That saves a seal and pour at every drop in a Class I area.
2) What hazardous location classes and groups is the Appleton ECS175 plug and receptacle approved for?
The ECS175 U-Line device covers Class I, Division 1 and 2, Groups B, C and D; Class II, Division 1 and 2, Group G (coal dust); and Class III. It also carries CSA Type 7BCD and 9G. Group G coverage is what makes it usable in coal handling and grain-type dust areas, not just petrochemical.
3) What size cord can I terminate in the ECS175 plug?
The plug accepts cable with an outside diameter of .538 to .639 inches. Measure the jacket OD on the portable cord you are landing; anything outside that window will not seal properly in the connector housing.
4) Will the Appleton ECS175 run a 2 HP motor at 250 volts?
Yes. The ECS175 is rated 125 or 250 Vac with 1 and 2 horsepower ratings, at 15 and 20 amps. For a 2 HP portable or plug-connected motor load at 250 Vac it is within rating.
5) How many poles and wires does the Appleton ECS175 have, and is it grounded?
Three poles, two wires, configured for grounded connections. That means two current-carrying conductors plus ground, so it suits 125 Vac line-neutral-ground or 250 Vac two-hot-plus-ground circuits. It is not a 3-phase four-wire device.
6) Is the Appleton ECS175 the same as an Appleton EFSR straight-blade device?
No. The ECS175 is a dead-front, factory-sealed ECS design. The EFSR/straight-blade line and the Contender sub-line use a different mechanism entirely, so plugs and receptacles do not interchange between them. If you are matching existing drops in a plant, confirm the installed devices are ECS before ordering.
7) What keeps water and dust out of the ECS175 receptacle when nothing is plugged in?
A neoprene gasket in the throat of the receptacle seals against either the plug body or the spring-loaded cover. With the plug pulled, the cover snaps shut onto that same gasket, so the opening stays sealed against water, dust and corrosive compounds in wash-down and outdoor industrial areas.
8) Will the ECS175 hold up in a corrosive or coastal plant environment?
The receptacle, cover, mounting box, connector housings, caps and ECP plug are copper-free aluminum (4/10 of 1% max copper) finished in epoxy powder coat. Copper-free aluminum is the standard call-out for refinery and chemical atmospheres, and the powder coat adds the corrosion barrier. Insulating blocks are fiberglass reinforced polyester for dielectric strength and low arc tracking.
9) Can I feed through to a second receptacle from the ECS175 mounting box?
Yes. The ECS mounting box is offered in dead-end or feed-thru entry, so you can daisy chain down a line of drops rather than home-running each one. Specify the feed-thru box when the device is mid-run.
10) What is the difference between the Appleton ECS175 and the ECSK-2023 set?
Same mechanism, different packaging. ECS175 is the base 15/20A ECS-series factory-sealed device, while ECSK-2023 is the packaged 3-pole set built around that same ECS mechanism. Order the set if you want the matched components together; order ECS175 for the base device.
11) Why choose a dead-front factory-sealed plug over a standard industrial pin-and-sleeve for a classified area?
In a Class I or II area a standard pin-and-sleeve gives you no protection from the arc drawn on make and break. The ECS175 dead-front design keeps live parts shielded and confines arcing inside the factory-sealed receptacle body, which is why no external conduit seal is needed at the device. Blade-type brass contacts maintain constant pressure across the full contact surface for the connection itself.
