GROUP SWITCH PANEL AHMA AHMA KSK150M

Enclosure for centralized protection for one inverter up to 150 kWp. IP44, wall-mounted, operating temperature min. -20°C. Rated current 240A. Includes Hager H3+ series compact circuit breaker with motor drive. Circuit breaker opening controlled by undervoltage release (230VAC). Opening occurs when an opening signal is received from the monitoring relay. Closing is controlled by motor drive (230VAC) when a permit to reconnect to the grid is received from the monitoring relay. A time relay ensures proper operation of the compact circuit breaker motor drive during closing. Compact circuit breaker lockable with a padlock. Production measurement implemented with a network analyzer (Circutor CVM-C11-ITF-IN-485-ICT2). Network analyzer equipped with ModBus communication interface. Local emergency stop switch located on the enclosure lid. 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 such an enclosure, the requirement for a separate AC safety switch is eliminated.
