Cooper Bussmann UL1449 3rd edition-recognized SPD solar apps
October 18, 2010 By Anthony Capkun
Colour-coded, modular plug-in and DIN-rail mounted design with voltage rejection feature and easyID visual indication makes the new Cooper Bussmann surge protective device (SPD) simple to identify, install and maintain. As the first UL1449 3rd Edition-recognized SPD for DC photovoltaic applications (in addition to IEC61643-11 compliance), it is simple to specify for solar power applications globally, asserts Cooper. Built-in, fast-acting short-circuit interruption (SCI) technology for 600vDC, 1000vDC and 1200vDC systems safely shunts damaging surges and overvoltages to ground. This capability also eliminates the need for additional fuses or overcurrent protection and associated panel space, says Cooper, providing PV users complete protection “at substantial cost savings”. The IP20 finger-safe SPD was designed with a voltage rejection feature to prevent misapplication, and colour-coded it for correct PV application.
