Fuse Holders and Systems

Mersen’s MDC 1500VDC fuse holders for 20x65mm fuses provide
advanced safety and protection for high-amperage utility-scale DC
distribution applications. These MDC15FH65 fuse holders are IP20-
rated for finger-safe operation and feature a rotating fuse carrier,
similar to the Mersen UltraSafe® line, ensuring safe and easy fuse
replacement.

The MDC15FH65 series is designed for use with the MDC DC
Distribution Series fuses, which provide superior current limitation
and coordination with other DC components. These fuse holders help
maximize system performance and reduce downtime.

Mersen’s 1500VDC HelioProtection fuse holders for 10/14x85mm gPV fuses introduce the next level of safety for Utility scale photovoltaic applications. The HP15FHM32 fuse holders are also IP20 finger safe, with a rotating fuse carrier like the Mersen UltraSafe® fuse holders. The US15M1HEL fuse holders are finger safe up to an IP20 grade of protection, and feature a pull out, pivoting fuse carrier. All bodies feature high performance UL 94 V-0 rated polymer material, providing superior flammability rating, with exceptional durability and dielectric withstand properties.

The HP15FHM32 series input and output terminals accept standard PV rated wiring and comb bus bars, providing added versatility for end-use installations.The US15M1HEL is designed with terminals to accept standard stock bus bar eliminating the need for custom combed bus bar, saving cost, time and simplifying installation.

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.
