GROUP SWITCH PANEL AHMA AHMA KSK075M-3F

Centralized protection enclosure for up to three inverters with a maximum power of 75 kWp. IP44, wall-mounted, operating temperature minimum -20°C. Rated current 100A. Includes a 125A load switch and a 150A contactor (sizing 1.5x In). Within the enclosure, separate cable protection devices MCN340E provide outputs for three inverters. The contactor is remotely controlled when a remote control signal is received from the monitoring relay. The contactor is closed when permission to reconnect to the grid is received from the monitoring relay. The main switch is lockable with a padlock. Production measurement is implemented using a network analyzer (Circutor CVM-C11-ITF-IN-485-ICT2). The network analyzer features a ModBus communication interface. The enclosure includes a local emergency stop switch on the lid. Contains a voltage and frequency monitoring relay Ziehl UFR1001E (compliant with SFS-EN 50549-1:2019); monitoring data can be duplicated if needed. When centralized protection is implemented with this enclosure, the requirement for a separate AC safety switch is eliminated.
