Cooper Bussmann is enhancing its suite of products for the protection of photovoltaic (PV) systems with the first European showing of its new combiner box range.
Developed for system builders and operators, the new combiner box offers protection, switching and monitoring of system arrays in a custom-built package. The company will have a ‘live' demonstration of the unit on its stand to show its full functionality which includes active monitoring of string current, system voltage, enclosure and external temperature, surge protection device status and switch status.
Alongside the new combiner box Cooper Bussmann will be featuring its new range of compact PV NH fuses. Available in three sizes – 200A, 400A and 630A – the line up is rated at 1000Vdc. With IEC, UL, VDE and CCC approvals, the entire line permits designers to create systems that are globally accepted. Designed specifically to protect inverters and isolate PV array combiner boxes and disconnects, these high performance fuses are capable of interrupting low overcurrents associated with faulted PV systems, such as reverse current and multi-array faults.
The PV NH fuses, with their compact dimensions and low power loss, provide simple and cost effective project design and installation, which is further enhanced thanks to their compatibility with existing NH fuse bases. The dual indication feature allows for speedy identification of faulted circuits and rapid replacement of the operated fuse.
Cooper Bussmann will also be exhibiting its new 1500Vdc fuse bases for use with its XL Style, square bodied fuse links including its highest rated fuse at 1500Vdc of 400A. This is the highest single voltage rating ever achieved by a fuse manufacturer in this package size, and represents a significant breakthrough in fuse design and performance.
