Overview

The nVent QLine E EMC Enclosure (SKU: Q18138PCEMC) is a Type 4X-rated polycarbonate junction box designed for industrial environments requiring electromagnetic compatibility (EMC) and environmental protection. This medium-sized enclosure measures 175x125x74mm externally and provides 169x119x67mm of internal space, making it suitable for housing control modules, power distribution components, or communication devices. Constructed from impact-resistant polycarbonate with an EMC-conductive coating in both base and cover, it shields sensitive electronics from electromagnetic interference (EMI) while resisting water, dust, and corrosion per Type 4X/NEMA 4X/IP66 standards. The light gray RAL 7035 finish features a contoured design with flush cover screws for a modern aesthetic and easier cleaning, with stainless steel cross-point screws and removable tamper-resistant caps. Internal mounting tracks and molded pads accommodate optional panels, rails, or PC cards, while a silver/silicone gasket ensures a watertight seal. UL 508A listed and cUL certified, this enclosure meets rigorous safety and flammability standards for use in chemical plants, food processing facilities, and outdoor installations where reliability and signal integrity are critical.
