Who Makes Pin and Sleeve Wiring Devices? Part 1

We’ve spoken about Pin and Sleeve wiring devices on this site before as well as the IEC standards it falls under We’ve also mentioned in passing some of the companies that make these products. In the first part of this series, we’ve compiled all of the major vendors of these products for North America. In future posts, we will begin to compare and stack vendors against each other. But for now, it’s worthwhile to understand the complete vendor landscape. In order to be fair, we will go in alphabetical order. Without further ado, here is every manufacturer of these products that distributes in the United States!

Company Overview

ABB is a multinational conglomerate that operates in in robotics, power, heavy electrical equipment, and automation technology areas. They have 132,000 employees worldwide and have a heavy presence in the North America in all of their divisions.

Product Offering

In a sentence, ABB’s Pin and Sleeve wiring device offering in North America has historically been “complete but not a strategic priority”. They offer both splashproof (IP 44) and watertight (IP 67) versions of their products as well a complete line of plugs, connectors, inlets, and receptacles.  They have three main offerings which mimic their catalog offering: industrial devices, high amperage products, and food & beverage. While the high amperage products are somewhat self explanatory, it’s worth noting that not all manufacturers go beyond 100/125A so this is a category where they might perform above average. Additionally, the main difference between their regular industrial Pin and Sleeve devices and their food & beverage line is that the latter are IP 69 rated. This means that they hold up to more extreme elements such as water and dust. It’s also critical to note that only the food & beverage line is advertised as UL/cUL Listed. It’s likely that these are the only products that are actively sold in the US/Canada.

New Developments

Recently, ABB came out with a new Industrial Wiring Device design and it looks has received some accolades:

It remains to be seen if they plan to put this line through UL testing. One thing’s for sure: once ABB decides to dive in, they will be a formidable force in the market.

Appleton (Owned By Emerson)

Company Overview

Appleton is wholly owned by Emerson Electric, one of the biggest electrical product and engineering firms in the United States.

Product Offering

Appleton’s UL product line specializes in Class Rated/Explosion Proof devices. In fact, 6 of their 11 product offerings are specifically Class Rated. Accordingly, most of their products are metallic and range from 30A all the way up to 400A. Whereas some of the other manufacturers in the United States offer a comprehensive product line, Appleton focuses mostly on receptacles (not plugs or connectors) that are both interlocking and non-interlocking. However, worth mentioning that they offer more plugs and connectors with their CSA line. In one sentence, their offering can be described as “explosion proof, metallic receptacles”.

Bryant (Hubbell Owned)

Bryant Pin and Sleeve

Company Overview

Bryant has a very interesting corporate background. It was founded in Bridgeport, CT and was the largest wiring device manufacturer in the world at one point. However, it ultimately dealt with labor issues and the company was sold to its current owner, Hubbell, in the early 1990s. Hubbell has kept the brand name on it’s products.

Product Offering

Bryant has a similar Pin and Sleeve offering from a pure product perspective to Arrow Hart, offering 16A-125A non-metallic plugs, connectors, receptacles, and inlets.  Bryant’s products are also UL/CSA listed. However, they do not carry the IP 69K rating but rather IP 67. In one sentence, Bryant’s Pin and Sleeve business is “safe, reliable, but Hubbell’s red headed stepchild in the Pin and Sleeve business”. It’s clear that Hubbell’s investment dollars have gone to the flagship brand over Bryant in the years following their acquisition through no fault of their own.
