GROUP SWITCH PANEL AHMA AHMA KSK250M-3F

Enclosure for centralized protection for up to three inverters with a maximum power of 250 kWp. IP44, wall-mounted, operating temperature minimum -20°C. Rated current 400A. Includes Hager H3+ series compact circuit breaker with motor drive. The enclosure has separate DC fuses /160A outputs for three inverters (fuses not included). Circuit breaker remote trip via undervoltage release (230VAC). Remote trip occurs when a trip signal is received from the monitoring relay. Remote close via motor drive (230VAC) when the monitoring relay provides permission to reconnect to the grid. A time relay ensures proper operation of the compact circuit breaker motor drive during closing. The compact circuit breaker is lockable with a padlock. Production measurement is implemented with 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 cover. Includes 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.
