Can you get a NEMA 4X enclosure with a short lead time?

Short answer

Yes. We offer a wide range of certified NEMA 4X and IP66-rated enclosures for harsh conditions, and we can deliver samples to UK customers within 24 hours; where an off-the-shelf product does not fit, we can produce a fully customised enclosure. NEMA 4X, defined by the U.S. National Electrical Manufacturers Association, covers indoor and outdoor use needing protection against corrosion, dust, rain, dripping and light splashing of liquids, as well as external ice formation. It is equivalent to UL 50 Type 4X and comparable to the IP66 rating under BS EN 60529. Our GEOS series is one such range.

Yes. We offer a wide range of certified 4X and IP66-rated enclosures to protect electrical equipment in harsh conditions, and where the turnaround is tight we can deliver samples to our UK customers within 24 hours.

The enclosure ratings specified by the U.S. National Electrical Manufacturers Association (NEMA) define what environmental conditions a given enclosure can withstand and how effectively it seals. NEMA 4X enclosures are suitable for outdoor and indoor applications that require a level of protection against corrosion, dust, rain, dripping and light splashing of liquids, as well as external ice formation.

These features make NEMA 4X standards equivalent to U.S. Underwriters Laboratories (UL) 50 Type 4X ratings, and comparable to the VDE 0470 (British BS EN 60529, European EN 60529) Ingress Protection (IP) 66 rating, which ensures resistance against dust and high-pressure jets.

Our GEOS series is one example. It is designed to withstand corrosion and prevent the ingress of dust, moisture, rain and liquid dripping, and you can see the full range at https://www.spelsberg.com/GEOS-Industrial-and-Outdoor-Enclosures/.

If off-the-shelf solutions do not fully address your needs, we are able to create fully customised enclosures that suit your intended application.
