Surge protection for photovoltaics
A color-coded, modular plug-in, and DIN-rail mounted design with a voltage rejection feature and easyID visual indication makes the new Cooper Bussmann Surge Protective Device (SPD) simple to identify, install, and maintain. The device is the first SPD for dc photovoltaic (PV) applications to be recognized by the UL1449 third edition, is IEC61643-11 compliant, and is simple to specify for solar power applications globally. Built-in, fast-acting, short-circuit interruption technology for 600, 1000, and 1,200 Vdc systems safely shunts damaging surges and overvoltages to ground. This high-performance capability also eliminates the need for additional fuses or overcurrent protection and associated panel space, providing PV users with complete protection at substantial cost savings.
