Certifications are of vital significance in enclosures for industrial control equipment because they maintain the original environmental protection rating even after the cutout. Take, for instance, Phoenix Contact’s Heavycon connector enclosure series, which conforms to the UL 508A standard.
The Heavycon connector enclosures are also certified for UL Type 4, 4X, and 12 protection categories for panel feed-through connectivity in electrical enclosures.
The UL 508A certification is critical for North American cabinet builders who produce UL-certified electrical enclosures for industrial control applications. That’s because enclosures complying with UL 508A standards must use components that have been evaluated and listed by the UL.
