New Switch Disconnector Protects PV and Wind Turbine Systems Erlangen, 2015-Feb-26 Siemens have expanded their portfolio of switch disconnectors for low-voltage power distribution. The new devices from the 3KD series were developed specifically for personal and system protection in photovoltaic plants and wind farms. The new six-pole model switch disconnectors are designed for PV systems in which high voltages up to 1200 V (DC) are generated. Siemens increased the permissible AC operating voltage tolerance of the three- and four-pole units from previously +5% to +10% as required by the IEC 60947 standard for wind farms. The 3KD switch disconnectors will now safely power down systems with voltages of 690 V AC (+10%). Siemens offers the units with integrated side wall-mounted rotary operator for left- or right-hand side mounting. The new devices from the 3KD series were deve...
