Mersen Electrical Power presents an extensive HelioProtection program that comprises 1500 VDC overvoltage protection devices for the protection of large photovoltaic production facilities, large scale DC or stand-alone (off-grid) installations. Among them, fuses, NH fuses, surge protection devices (SPDs), power distribution blocks (PDB) and DC switches are available. In addition, the HelioProtection range of gPV fuses is also enriched thanks to two NH-style gPV fuses, 1XL and 2XL fuses that work from 50 to 250 A, for low power applications.
Regarding overcurrent protection for inverter & storage, Mersen offers EVpack-fuse and M-fuse as fast-acting DC fuses engineered to meet specific needs in EV/HEV and battery storage systems. They are protected from 100 to 1000 VDC and up to 600A with Minimum Breaking Capacity. The HS-ES product line features a high cycling performance DC protection device which clears both high and low-fault current at 1000 VDC in less than 1 ms. Last, the SB PCB is a plug-in surge protection for PCBs. It is a series of socket bases that allows for integration of IEC surge protection cartridges directly on printed circuit boards.
