By 2016, all UL1449 3rd Edition SPD’s will be required to test and publish a short circuit current rating (SCCR) and pass the intermediate current tests in order to comply with the SPD component assembly standard.
The SCCR of an SPD as defined by UL1449, in accordance with Article 100 of the National Electric Code (NEC), is the maximum short circuit current from which an SPD can safely disconnect during a fault situation. The intermediate current tests require that the SPD survives the application of three additional fault current levels of 100, 500, and 1,000 amps.
CITEL, specialized Surge Protective Devices (SPD’s) manufacturer, offers its VG line of photovoltaic solar SPD’s which are UL 2016- ready. These include DS60VGPV and DS50VGPV series devices. These DC SPD’s are specifically designed for PV solar applications and provide optimal protection for inverters and combiners. CITEL products not only meet UL’s stringent requirements but exceeds them. CITEL’s VG Series of SPD’s is one of the only products available that does not require overcurrent protection and that will also provide an SCCR for up to 100kA.
The 2016-Ready SPD’s also feature CITEL’s patented VG Technology. VG Technology provides the following surge protection benefits:
-Up to five times the life expectancy of MOV-only SPD’s
-Elimination of leakage current
-Elimination of working current
-Will meet UL standards with no conditions of acceptability
-10 and 20-year free replacement warranties
