August 17, 2020 - Avon, OH -Polycase, a leading US manufacturer of plastic enclosures, has introduced two new NEMA enclosure lines for the electronics and electrical enclosure market. Engineered for versatility, the new ZH Series and ZQ Series boast a dynamic list of attributes. A modern gray aesthetic offers appeal for high-end products while the industrial grade quality and durability benefit everyday applications. The new NEMA enclosures can be used in industries such as alternative energy, agriculture, oil & gas, telecommunication, food & beverage, marine and many more.

Molded from premium impact-resistant polycarbonate, the new series are weatherproof, waterproof and corrosion-resistant for use in harsh environments.

Tamper-resistant screws and an area for a padlock offer added security for sensitive devices susceptible to unauthorized access.  Strengthening ribs designed into the feet and flanges provide added durability for surface-mounted applications.

Designed for versatility, these enclosures have four separate internal mounting panel options that allow panels to be mounted in the cover, bottom of the base, top of base or suspended at any height within the base with the use of an easy-to-assemble suspension kit. The suspension kit offers dual purpose functionality as a hinge kit for the panel enabling easy access to components below a top mounted panel. Modular mounting bosses in the base and cover provide flexibility for mounting additional components. Available accessories include panel kits, pole mounting kits, DIN rail kits, cable glands and vents.
