AC side protection
GEWISS products for AC side protection can meet all system requirements in the residential, commercial and industrial sectors, with an extensive product range, from modular devices to moulded-case circuit breakers, modular accessories and distribution boards.
Modular AC devices
§ LST surge protection limiters, suitable for AC side protection from overvoltage generated by atmospheric discharges, for maximum inverter service continuity. The limiters are also available in versions with integrated auxiliary contact, to remotely indicate the end of life of removable cartridges.
§ Type B residual current circuit breakers, for protection from AC side indirect contacts, in situations where inverters without transformers are installed or the inverter is constructed in such a way as to prevent direct current dispersion to earth due to faults.
Moulded-case circuit breakers and metal distribution boards
The selection of MTX moulded-case circuit breakers and the 47 CVX range are the ideal solution for protecting the AC side of large photovoltaic systems. The CVX metal distribution boards for indoor environments can be completed with the MTX circuit breakers which offer notable potential in terms of calibration and breaking capacity, thereby meeting every installation need.
Empty, string or parallel enclosures and modular boards
The range comprises 40CDK_IP65 enclosures and boards in 4 to 72 module versions, for countless configurations and for protection and parallel solutions in small and large-scale photovoltaic systems in the industrial, commercial and residential sectors. The operating voltage (Ui), equal to 1000V DC, enables latest-generation, high performance inverters to be used in the field, to maximise photovoltaic system productivity. The excellent IK09 impact resistance, the IP65 degree of protection and configuration for safety locks and leadable panels ensure professional installation and the utmost safety for operating continuity. The enclosures and boards are also available as prewired versions.
