Soule PBD DC Disconnect Switch
The PDF DC Disconnect Switch is a high quality, extremely robust product. This safety device is simple and transparent to the network, and reliable over time and in all environnements. Our PBD is a deformable switch, which will move with the expansion and retraction of the your bussbars systems eliminating the needs for flexible shunt connections.

PBD DC Disconnect Switch is mainly used with aluminum bussbars systems. The PBD switch is welded directly onto the aluminum buss bars systems. The electrical contact is made through silver contacts which give it a strong mechanical endurance with very good electrical data.
