Dynamic Battery Sales & Service (DBSS) has developed a unique, patented approach to battery safety. The Top Terminal and Side Terminal line of battery disconnects improve the installation and safety of any VRLA battery in any type of back up power application.
The U.S. National Electrical Code (NEC) generally requires that all conductors be protected from overcurrent (Article 240). This protection can be in the form of fuses or circuit breakers listed for the application (especially DC voltage) and 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 burn up the power cables in the event of a fault condition. This can lead to significant equipment damage and lost revenue without over current protection.
The fused termination kits offer the addition of a fuse at the battery where it can provide the most protection. 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 VRLA batteries and can be retro-fitted to new releases or brands not currently serviced.
The circuit breaker versions can be furnished with a shunt trip option that can be used to implement the Emergency Power Off (EPO) requirements of NEC Section 645.
