At long last, we’ve reached the last section of our manufacturer’s guide for pin and sleeve wiring devices. If you haven’t read Part 1 or Part 2, we would highly suggest that you do that now. Without further ado, let’s get on to Part 3!
Mennekes is a smaller, privately held German company. They started in the United States roughly 30 years ago and have a full line of UL Listed pin and sleeve wiring devices. Their worldwide revenue is likely somewhere between $100-200 and their specialty is pin and sleeve. Mennekes is the market leader in Germany.
Mennekes has a complete line of IEC 60309 products. This includes plugs, connectors, receptacles (switched or non-switched), and inlets. Overall, Mennekes has very high quality and is on par with Hubbell. In the US, they are considered to be second or third in market share in the US. Mennekes supports amperages from 20-100A; however, they have different product designs for different amperages. For example, their 20A plugs look like this…
…while their 60A plugs look like this…
While both have a similar function, the design advantage clearly goes to the 60A and 100A pin and sleeve products. It will be interesting to see if the company standardizes in the coming years. One thing that Mennekes offers that no other IEC 60309-2 manufacturer can are their combination units. This allows multiple pin and sleeve wiring devices to be placed within a single enclosure.
However, unlike Meltric and Hubbell, Mennekes does not offer a switch rated product. With Hubbell entering the market recently, it will be interesting to see if Mennekes counters and introduces a similar product. They also do not have an IP69k rating on their pin and sleeve line (they only have an IP69 rating).

RussellStoll (Owned by Thomas & Betts/ABB)
Russellstoll is the pin and sleeve wiring devices offering from Thomas & Betts, an American company that was purchased by ABB in 2012 for $3.9B. They still choose to carry the Russellstoll name in the United States and is what you’ll most commonly hear out in the field
Russellstoll offers three separate product lines for their pin and sleeve wiring devices:
Standard IEC 60309 Line
Russellstoll’s standard pin and sleeve offering is actually under the ABB name. It is essentially a UL adapted version of ABB’s international line which was covered earlier. Their amperages range from 16 up to 125 Amp, up to 600V, Watertight to IP67 and IP69K.
In general, we don’t see these products too often in the US market. However, they are perfectly suitable devices.
DuraGard Waterproof Line
This DuraGard line is a pin and sleeve (but not IEC 60309 compliant) product line that was developed as a competitive product to Hubbell’s Twist Lock products and only go up to 60A. Because they do not follow the standard, we will not cover them in great detail but you should be aware that these exist in the market and are a solution sitting between Twist Locks and true pin and sleeve.
MaxGuard Explosion-Proof Line
Russellstoll’s most dominant product line is undoubtedly their explosion-proof products. They are considered a market leader in this space and compete with Appleton (also covered earlier) for first place. Most of their products are metallic and range from 30A to 400A. To compliment this line, they also have a wide range of mounting options for receptacles and inlets. Often times, you can tell which product lines a company prioritized by the length of their catalog. Russellstoll’s explosion-proof catalog is longer than the two catalogs above combined.

Scame is an Italian company that specialized in wiring devices. They are a private company and were founded in 1963. Scame’s primary product lines are pin and sleeve wiring devices.
Scame manufactures pin and sleeve products to the IEC 60309 standard and entered the North American market a few years ago in an indirect way. Traditionally, a company has to go through distribution to gain a foothold. However, Scame largely used an online approach and partnered with ElecDirect to allow their products to be purchased online. Also, they have not gone through the trouble of getting their products UL Listed (only UL Classified – here’s the difference). However, they do offer a full product line from 16A to 125A and are IP 67 rated. We have heard that some customers are fine without a UL Listed product and this is a cheap, easy alternative to buying Hubbell through traditional distribution. It will be interesting to see if Scame gains traction in the US.

Walther was founded in 1897 and is headquartered in Eisenberg, Germany with full-service subsidiaries in The United States, The United Kingdom, France and Austria. They are a direct competitor with Mennekes in Germany.
Walther carries a full line of pin and sleeve. Their international offering is IP 44 and their domestic offering is IP 67. Because they are not IP 69 rated, you won’t find Walther in extremely harsh environments such as food processing or chemical manufacturing. Additionally, they also do not offer an explosion-proof or other specialty lines.
However, Walther is the only pin and sleeve manufacturer in the United States who has been able to get their compression-style strain relief system (the back of the plug – white crank piece below) through UL testing. This has allowed them to compete in the data center market and is likely their most successful industry application. As you can see, they even have a separate catalog around their data center program.

Woodhead is the wiring device offering from Molex, a 10,000+ person company headquartered in the United States that sells and distributes advanced electronic components and solutions.
Woodhead offers a very limited “true” IEC 60309 pin and sleeve offering. For North America, their products range from 20-100A and have IP 67 ratings but Woodhead just does not invest much in their pin and sleeve product line:
So, why are they included in this guide? Well, it’s quite simple. Woodhead is widely known in the market as a Twist Lock alternative in wet environments. They are the leader in watertight and waterproof lower amperage wiring devices and you will see these “yellow goods” on manufacturing floors throughout the country. Here’s the more common Woodhead product you’ll see in the market:
