Cooper Crouse-Hinds are premier manufactures of high quality and robust enclosure solutions and assemblies configured to meet the requirements of the most demanding hazardous area and industrial environmental applications. With over 30 years of experience in the design, engineering and manufacture of enclosure solutions, Cooper Crouse-Hinds provides, tried and tested solutions to meet the toughest project and installation needs.
The STB range is an “ATEX certified” heavy-duty junction box solution fully compliant with the impact, thermal and ingress protection requirements of EN50014. These are available in a wide range of sizes to meet a diverse range of applications.
With our customizing service fittings such as cable glands, breather drains and blanking plugs can be provided and fitted as specified. Additionally appropriately certified components such instrument transmitters and field-bus modules maybe fitted to provide fully certified OEM solutions.
Using the highest quality materials and design benefits the STB junction box range is the industry benchmark for quality and performance enclosure solutions for both electrical and instrumentation applications.
The retained stainless steel slotted hex bolt fastenings provide a rapid means of achieving high integrity ingress protection (IP) of 66 for reliable & rapid environmental protection.
A high integrity “single piece” sealing gasket for superior ingress protection (IP) of 66 and excellent recovery and re-sealing properties for continuous environmental protection.
Superior ingress protection is enhanced by the wide ingress sealing path of the junction box and the use of blind nutserts that eliminates any potential ingress from the lid fixing bolt.
An integral external & internal feed through brass earth / ground stud assembly enables rapid and reliable protective earth / ground connection mounted on the side of the enclosure for ease of access.
