DC Power Disconnector, Emmergency Button

Model ZDK31-125, forklift & golf cart power disconnecting button

Overview:

The ZDK31-125 is a SPST (Single Pole Single Throw) DC power disconnector, designed to provide a rapid means of disconnecting batteries or other power supplies in the event of serious electrical faults. Whilst the switches are primarily intended for use with battery powered vehicles, they are also suitable for use with static power systems. ZDK31-125 is capable of safely rupturing full load battery currents in the event of an emergency.

Modern battery powered electric vehicles are inherently very reliable and safe. However, even when sophisticated electronic controllers are used, it is desirable to have a means of disconnecting the battery in the event of an emergency, such as a vehicle failing to stop or an electrical short circuit. In many countries, it is mandatory to fit one or more devices to achieve an emergency disconnection of the battery.
