Safety Engineered

The addition of our patented DC disconnect allows your service professionals to disconnect any given battery plant from the rest of the power system and therefore the network. With the switch in the "off" position or the fuse removed, any technician can safely perform maintenance duties on each individual battery string. This removes the threat of a voltage fluctuation or even a short to ground being visible to any traffic carrying equipment.

Fused or Circuit Breaker

Fused and Circuit Breaker products are easily installed for any specific battery system or DC disconnect application. In many cases, the same cables can be utilized reducing the time and expense of retrofitting.

Communication Power Solutions Inc. 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 that are 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.

Fused termination kits offer the addition of a fuse at the battery where it can provide the most protection. However, 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.

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.
