DC Disconnects has developed a patented approach to battery safety, which is both unique and cost effective. The Top Terminal and Side Terminal line of battery disconnects improve the ease of installation maintenance and overall safety of any VRLA battery system in any type of back up power application.

The U.S. National Electrical Code (NEC) generally requires that all conductors be protected from over current faults (Article 240). This protection can be in the form of fuses or circuit breakers that are listed for the application (especially DC voltage). The protection device must be rated to interrupt both the nominal current and the possible fault current due to short circuits.

The batteries used in any back-up power system can damage the power cables in the event of a fault condition without over-current protection. This can lead to significant equipment damage and lost revenue.

Any of our termination kits offer the addition of a safety interrupt at the battery where it can provide the most protection, by safely taking a battery system offline.

For those applications where a fuse is not the correct solution, the same basic assembly is available in a circuit breaker version with many of the same advantages as well as a remote trip capability.

Generally, fuse and circuit breaker models are available in current ratings ranging from almost zero to 4000 amps. (Most typical applications range from 200A to 800A.) These products are available for most brands of VRLA batteries. (GNB, Douglas, C&D, Deka & Lucent, etc).
