Indoor-Outdoor
NEMA 4X enclosure with indoor-outdoor compatibility provides rugged protection for washdown zones and outdoor sites, reducing corrosion risk and simplifying installation. This directly lowers maintenance costs and extends service life, resulting in a lower total cost of ownership in demanding environments. Applications include control panels exposed to moisture, dust, or incidental splashes in manufacturing facilities and outdoor installations. Copper windings and an epoxy-encapsulated construction boost reliability and moisture resistance, improving thermal performance and short-circuit tolerance to prevent downtime in critical automation loops. The 5 kVA rating at 60 Hz with primary options of 240 V and 480 V, and secondary 120/240 V, supports standard industrial power architectures and flexible panel design for automation equipment. The 2-tap voltage adjustment (+2.5% FCAN; -2.5% FCBN) enables precise voltage regulation, maintaining device tolerance in fluctuating supply conditions, which is essential for PLCs, sensors, and relays. Weathershield indoor-outdoor capability and an 80 °C rise rating ensure dependable operation across varied temperatures, reducing the need for additional enclosures and simplifying installation in outdoor or harsh indoor environments. Overall, these features contribute to easier retrofits, faster installation, and improved ROI in modern automation projects.
