ARCON 3G presents effective modular and compact system for arc protection in low voltage switchgear assemblies, which successfully provides both, personnel and assembly protection. ARCON 3G detects an electrical arc caused by a short circuit through optical sensors and the load current input on the system to employ the fast clearance of arc faults on an electrical system with a total arc mitigation time less than 2 ms.
Figure 1.2 Comparison of impact timing for systems with and without ARC protection Functional scope The ARCON 3G protection system is designed as modular system, so that flexible use in different switchgears is ensured. The ARCON 3G system provides following modules which can be used to establish...

ARCON 3G ARCON 3G complex arc protection system The ARCON 3G complex arc protection system can link up to 5 extended systems together with MASTERLINK connection. With ARCON 3G complex arc protection system it is possible to provide line or ring topology for the purpose of redundancy. Main purpose of MASTERLINK is to share current criteria between master units.
Mounting instruction DIN Rail modules All ARCON 3G modules are designed for DIN rail TS35 mounting to ensure quick and easy installation. For installation in a switchgear cabinet safety distance to adjacent components and cabinet parts like internal shrouding, door and side panel is required.
