Electrical E-Commerce: How To Buy Motor Disconnects Online (Part 1)

gamut hubbell rotary disconnect

Local motor rotary disconnects are a hot topic on our site. For new readers, here’s a recap of some of our older posts about disconnect switches:

Today, we are focusing less on the product itself and more on how to buy it. Specifically, we wanted to give you tips on the best sites to find and purchase these products online.


The Criteria

We wanted to make sure this was specific enough to evaluate across a level playing field. Therefore, we are choosing to evaluate companies that have at least a standard 3 pole, 30A, NEMA 4X (up to 600VAC) non-metallic rotary disconnect. We are also only considering companies where you can buy without being a member. Said another way, only companies that offer up-front pricing on the internet for all to see will be considered.

Without any further delay, here are the best places to buy motor disconnects online!

Best Vendors to Buy Motor Disconnects Online

Automation Direct

automation direct - buy motor disconnects online



Company Description

From their website, here’s how Automation Direct describes themselves

Automationdirect.com, originally founded as PLCDirect in 1994, has quickly grown from a tiny PLC company to a well-recognized name in the Industrial Automation Market. As the first industrial controls company to successfully use a direct sales catalog for PLC products, Automationdirect.com is now setting the standard online in industrial control sales.

Disconnect Offering

Automation Direct carries Bryant disconnects/motor controllers. They offer both a 30A and 60A product offering for an enclosed, NEMA 4X AC disconnect and prices start at $110.00 for a standard 30A disconnect. In our opinion, this is pretty good pricing and Bryant is well known in the market (check out our analysis on Bryant here). Here are some of the features of the Bryant disconnect as explained by Automation Direct:

Final Thoughts

Automation Direct offers free 2 day shipping on orders over $49. This is great for customers who are making regular MRO purchases. We’ve discussed Amazon Prime’s entrance into the B2B industrial world at length. Automation Direct is a strong enough player in the market to basically match Amazon with fulfillment and delivery. They are also very well review by their customers and boast a 98%+ satisfaction rate:

Overall, Automation Direct does not offer a wide selection nor is it their primary focus. However, their pricing is competitive and they are well respected and well known brand. This makes them a perfectly suitable place to buy motor disconnects online.


Allied Electronics

Company Description

Here’s Allied Electronic’s self description from their company website:

With more than 3 million parts online, engineers and purchasers look to Allied for a broad range of products from more than 300 world-class suppliers. Allied’s strong supplier relationships, and status as an Authorized Distributor for all their suppliers, are a key strength in maintaining high standards of product quality and availability. The breadth of product offering means that Allied is able to satisfy the needs of customers from all areas of industry and commerce.

Disconnect Offering

Allied has a very strong range of tier one motor disconnects available for purchase on their site. Again, for only the criteria above (3 pole, 30A, NEMA 4X non-metallic rotary disconnect), they can offer the following suppliers:

Altech Corp KKVM332 Y/R Motor disconnect


Schneider Electric MD3304X motor disconnect


Hubbell Wiring Device-Kellems HBLDS3 motor disconnect


You can see there’s a wide variation in pricing as well as availability. There are 109 Schneider disconnects in stock but no Altech. There’s also over a $100 price variance between the lowest and highest priced items

Final Thoughts

Based on our research, it does not appear that Allied offers free shipping. Perhaps you need to have an account before those kinds of offers become available. The true differentiator for Allied is the selection of brands available. Allied may be the most complete offering for those looking to buy rotary motor disconnects online.
