New ASO solar fuse (gPV) – Meets both IEC 60269-6 and UL 2579 photovoltaic standards

SCHURTER successfully introduced the ASO solar fuse in 2010. The ASO now meets both IEC 60269-6 and UL 2579 standards for the protection of photovoltaic systems, thus it is qualified for use according to the latest gPV requirements.

The ASO solar fuse has been specifically designed for the protection of photovoltaic systems. This fuse can safely protect PV modules and conductors from reverse overcurrent conditions.

As PV systems have grown in size, so have the corresponding voltage requirements. This increase in system voltage has typically been intended to minimise power loss associated with long conductor runs. Standard circuit protection devices are not designed to completely protect photovoltaic panels. However, the ASO solar fuse is UL listed to safely interrupt faulted circuits up to this demanding volt-age level.

SCHURTER offers 13 different ampere ratings to match specific requirements of various applications, such as inverters and battery charge controllers or to be used as inline or string fuse. A PCB version and bolted contacts are also available on request. Moreover, SCHURTER provides the appropriate touch-safe fuse holder (FSO) and fuse clip (231660).

The product includes UL approval and is RoHS compliant. VDE approval is currently in process.

Technical features:

- Standards: IEC 60269-6 and UL 2579

- Current range: 1 A to 30 A

- Rated voltage: 1000 VDC

- Breaking capacity: 20 kA @ rated voltage

- Min. interrupting rating: 1.35 x In
