See ARCA T in action
Experience how the ARCA T combines instant visibility with rugged protection. This UL-certified solution for the global market ensures you never have to choose between seeing your components and keeping them safe.
See More. React Faster. Protect Better.
In modern industrial environments, every second counts. The ARCA T allows you to monitor critical components, HMI displays, and status indicators at a glance without ever opening the cabinet. By eliminating unnecessary door openings, you maintain full IP66 and IK09 protection while significantly reducing the risk of electrical shock and downtime.
-
Instant Visibility: Check system status, fuses, and alarms immediately.
-
Uncompromised Safety: Keep the cabinet sealed to protect both equipment and personnel.
-
Operational Efficiency: Streamline maintenance routines with quick visual inspections.
Robust Protection Meets Smarter Design
Unlike traditional steel or GRP cabinets that require separate, glued-in window installations, the ARCA T comes ready for action. Our innovative single-moulded transparent door offers superior impact resistance and a clean, professional aesthetic.
-
UV-Stable Smoked Polycarbonate: Our smoked door prevents yellowing and maintains clarity even under intense sunlight.
-
Corrosion-Free Performance: 100% corrosion resistant, making it the ideal choice for harsh outdoor and industrial settings.
-
Seamless Integration: Fully compatible with the existing ARCA range and accessories.

Setting New Standards in Industrial Monitoring
The ARCA T is the perfect partner for sectors where constant monitoring and high-level protection are equally critical. In the energy transition and green energy sectors, it protects the heart of renewable infrastructure, while in water and waste water management, it provides reliable performance in highly corrosive environments. For factory automation and IoT, the transparent door offers clear visibility for smart control systems and HMI displays. Even in public infrastructure and traffic control, the ARCA T stands as a durable shield for vital networks.
Available sizes
While the ARCA T is available in a wide variety of configurations to suit any project, common sizes include the compact 300 x 200 x 150 mm model and the larger 600 x 400 x 210 mm version. You can choose between standard DB3 locks or the ergonomic swinghandle option for enhanced access control. In addition, a separate mounting plate (2 mm galvanized steel) is available for each size.
