3 dni temu · I’m planning to use NH fuses in a disconnect holder to enable me to isolate the power at several points in my new off-grid system. I have 2.5kW PV generation per string feeding a Victron 250/60 MPPT controller to charge a 48V battery (2x 24V 200Ah Victron Lithium Smart connected in series). I have a Phoenix 48V 5000VA inverter to connect to the batteries. At some point in the future I want ...
Mersen is the first manufacturer to offer screw-less, spring pressure, wire termination technology into a power fuse holder, delivering the best of both technologies to its customers. Now you can experience the combined benefits of safety, ease-of-use, labor savings and reliability of UltraSafe fuse holders and spring pressure technology.
E 90 fuse holders and fuse switch disconnectors provide protection against short-circuits and overloads. The fuse disconnector can be sealed or padlocked to ensure the operator’s safety during maintenance.
CUS101HEL series are specially designed for the protection of PV systems. Modular fuse-holders are finger-safe under IEC and UL standards to an IP20 grade of protection, including fuse changing (with the flick of a finger).
E 90 PV fuse disconnectors have been specifically designed for photovoltaic applications. Thanks to their rated voltage up to 1000 V d.c. they are the ideal solution for protecting cells, inverters or surge arresters. In case of maintenance, they ensure isolation of circuits and strings up to 1000 V in direct current, in total safety.
Inside d.c. combiner boxes, PV strings are protected with cylindrical fuse‑links inserted in cylindrical fuse holders. In the world of photovoltaic systems, ensuring the safety and optimal performance of PV modules is of paramount importance. One critical aspect of this is the protection of PV strings against reverse currents.
Each add-on kit includes five fuses and five fuse holders for easy and secure installation and replacement. The add-on kits contain the following approved fuse types (additional types available by request):
