Cable Gland Approvals: Connecting Two Different Worlds

Today, we live in two worlds when it comes to approvals for explosion-proof cable glands.  

We have the ATEX (IECEx) mainly found in Europe. Then, we have the UL Class/Div world—well-known in North America, especially here in the United States.

Although there are good reasons to use either the ATEX or UL, there is a need out there for a single cable gland that can be used worldwide and isn’t restricted to just one market. This is still the biggest challenge when looking for the perfect cable gland. 

Why is this? The reason is due to UL Class/Div requires different test parameters than ATEX, with its own test methods for impact and a 30 BAR static pressure test that may require a different design.  As a result, this makes it almost impossible to also include EMI (electromagnetic interference) protection.

Along with demanding outstanding quality, the market needs an economical and smart cable gland solution. This means a small footprint with optimal EMI protection as well as a simple assembly concept—saving both time and money.

All-in-One Solution Coming to Global Market

Here at Sealcon, we listened, and we rose to the challenge. In order to meet the global market demand, we streamlined our cable glands to bring you an all-in-one solution: The Metal Ex Cable Gland.

Learn more about our Sealcon Metal Ex Cable Glands.

This innovative cable gland covers all three ATEX, IECEx, and UL Class/Zone approvals—reducing supply chain and engineering efforts as well as time and cost for market-specific production and approvals. 

Along with the existing ATEX / IECEx approval, our Metal Ex Cable Gland series is now certified cCSAus for Class/Zone, which allows you to use the Glands in Class I and II Division 2 applications after NEC codes 501 and 502.

With that, we’d like to share 4 steps to get your application ready for UL Class/Div:

• Choose thread size and cable diameter range
• Get cCSAus class/zone file, check NEC Article 501 with clauses 37.3 and 37.4
• Check cCSAus class/zone markings on the bag label (the gland itself only shows an ATEX / IECEx marking)
• Hand over cCSAus class/zone file to your UL/CSA inspector, pointing out NEC Article 501
  
  

Sealcon’s Full Line of Ex-e/Ex-d Cable Glands:

Our complete product line of Ex cable glands is designed for Hazardous Areas and increased safety locations and all of them provide these key benefits:

Unique Product:
The patented recess form seal guarantees NEMA 4x & NEMA 6 (IP68 / IP69K) at 150 PSIG (10 BAR)

Pull-out Resistance & Cable Protection:
Overlapping clamping splines apply a concentric force, preventing the form seal from being pulled out of the gland. This ensures pull-out protection without damage to the cable.

Liquid Tight:
Machined O-Ring Groove: All or our Ex Cable Glands come with an O-Ring, resulting in a Liquid Tight Seal between cable gland and installation.

Time Saving Installation:
Simply push the cable through Cable Glands – Tighten Dome Nut Done! No disassembly of the cable glands required!
