Fuse Holders and Systems

Fuse supports, fuse disconnect switches and accessories from 2.4kV to 38kV.
Fuse supports, non-disconnecting, are used primarily in potential transformer circuits, or where there is some other disconnecting or isolating device in series with the fuse in the circuit. Disconnecting switch devices have the additional feature of serving to isolate the equipment they protect. It should be noted that disconnecting switches are not load-breaking devices, therefore, the circuit must be open prior to the fuse disconnection. Select either a fuse support or a disconnecting switch for each fuse. Fuse supports and disconnecting switches include live parts for both ends. Both fuse supports and fuse disconnect switches can be mounted vertically or horizontally. The type EK are used for indoor installations while the type EKO are used outdoors.

Mersen’s 1500VDC HelioProtection fuse holders for 20x65mm PV fuses introduce the next level of safety for higher amperege utility scale photovoltaic applications. The HP15FHP80 fuse holders are finger safe (IP20 ingress protection rated) and feature a rotating fuse carrier similar to the Mersen UltraSafe® fuse holders.

The HP15FHP80 series offers two configurations to fulfill global market requirements. One configuration offers input and output terminals that accept standard PV rated wiring and comb bus bars, providing added versatility for end-use installations. The second accepts wire and bus bar terminations. The body features high performance UL 94 V-0 rated polymer material, providing superior flammability rating, with exceptional durability and dielectric withstand properties.
