NH fuse links for battery storage protection
The use of batteries is growing due to the utilization in renewable installations.These batteries shall be appropriately protected against overcurrents that could shorten its life, specially against short-circuits, that shall be interrupted in a very short time. NH BATTERY STORAGE fuse-links from DF Electric are capable to clearing all types of overcurrents, overloads and short-circuits, thus the fuse-links protect the batteries as well as cables and all switchgear of installation.
These fuse-links are designed and manufactured with the same techniques that semiconductor fuse-links, which makes them very fast of operation and gives a good performance under continuous charge / discharge cycles. They are optimized to have reduced power dissipations that allow the utilization of a wide range of fuse-bases, disconnectors and fuse-switch-disconnectors. NH BATTERY fuse-links range comprise five sizes NH000, NH00, NH1, NH2 and NH3 with rated currents between 20A and 630A, with working voltages up to 440 V DC and 550 V DC. These fuse-links can be used also as a protection in other DC applications, but it is very important to take into account the kind of load and the time-constant of circuit in order to have a correct application (consult us).
