With an IP66 ingress protection rating, this enclosure offers comprehensive defense against dust and strong water jets, making it suitable for demanding industrial, construction, process plant, and hazardous area environments.

This model provides a robust housing measuring 255 x 250 x 120 mm, allowing ample space for wiring and component assembly. Designed to accept up to 20 electrical terminals, it is ideal for complex circuit distribution or control gear installations, supporting both retrofit and new-build projects.

Its construction from antistatic, high-impact polyester SMC & DMC ensures mechanical integrity and long-term corrosion resistance, even in aggressive atmospheres. The enclosure is flame retardant to IEC 92.1 and UL94VO, shock resistant, and includes pre-punched fixing holes for easy mounting. It is further equipped with an external earth connection, enhancing operational safety in hazardous zones.

Certified in compliance with the latest European ATEX directives, BASEEFA, and RoHS standards, this junction box supports use in potentially explosive atmospheres, including Zone 1, with increased safety per EN/IEC 60529 IP66 and EN 50014 classifications. The box operates in temperatures from −25°C to +40°C as standard, and from −55°C to +65°C for extended ranges, accommodating the requirements of many industrial and automation sites.

Typical applications include connecting additional sockets or circuits, extending lighting points, performing electrical repairs, and safely housing control gear or instrumentation interfaces. Its combination of high current rating (11.5A), 8-way configuration, and large, clearly defined enclosure makes installation straightforward and maintenance efficient.

Package includes: 1 junction box, 4 mounting screws, and an instruction sheet. No terminals are included with the box.

Widely used in sectors such as industrial automation, oil and gas, chemical processing, general manufacturing, construction, and infrastructure projects, the Bartec GB 255-730385 ensures safety, compliance, and reliability for critical power and control systems.
