Mersen launches new fuses as well as switchgears for 800 V AC-equipped PV systems

• The French maker has broadened its item profile with new products particularly created for photovoltaic or pv systems with 1500 V DC/ 800 V AC inverters. The new deal consists of NH merges as well as horizontal and upright fuse switch-disconnectors.

Mersen, the French professional in electric protection, control items and power management, has actually introduced a brand-new series of merges as well as devices for solar systems with 1500 V DC/ 800 V AC inverters.

"Today, a growing number of new photovoltaic systems are using string inverter solutions without DC merges," the firm explained.

The supplier enhanced the AC result voltage of the inverters to 800 V in order to minimize investment cost and also power losses. This service calls for 800 V AC security in the AC mix boxes which team with each other numerous string inverters. "The optimal security at this voltage degree is the combination of NH fuses with NH fuse switch-disconnectors: this is the only integrated remedy to shield, isolate as well as switch the circuit," Mersen specified.

The producer has completed its product line with new 800 V AC fuses which can disturb any type of present overload, and also a damaging current of approximately 90 kA as well as at a checked voltage of 880V.

"Mersen is now the only maker to supply a total set of NH integrates and NH fuse switch-disconnectors created specifically to fulfill the defense and distribution needs of power grids on the AC side of brand-new string inverters with a small operating voltage of 800 V AC. This new deal consists of NH integrates and also NH fuse switch-disconnectors, in straight version (Multibloc) as well as upright version (Multivert)," it more discussed.

Mersen deals NH 800V AC integrates of 50 A to 160 A (size 1) as well as 200 A to 250 A (size 2) and obstructs compatible with dimension 1 in its Multivert variety, and with dimensions 1 as well as 2 in its Multibloc array.
