RETTBOX® and RETTBOX®-air: vehicle ignition-activated connection ejector systems

With a Rettbox® or Rettbox®-air installed on an emergency vehicle, asset damage caused by driving off prior to disconnecting the charger power or compressed air can be avoided.

The Rettbox®, a watertight enclosure with power inlet, is the on-board connection point for parked vehicles. Rettbox®-air offers a compressed air feed as well. When the vehicle ignition is activated to drive to an incident, an electric pulse ejects the coupler socket from the Rettbox® housing without any need to disconnect manually.
Its lid drops automatically to close the unit protecting the inlet from road dirt.

The socket is a Marechal decontactor type using spring-loaded butt type contacts. It is this technology that enables a rapid, frictionless and load-break disconnection.
The system is robust and reliable. For this reason the Rettbox® has been installed in its thousands across Europe in fire engines, emergency ambulances and police vehicles.

Its compact design allows easy retro-fitting to existing vehicles as well as first-fit into new vehicles. The Rettbox®-air is available for 12V, 24V, 230V as well as 400V for the Rettbox® at 20A and 32A ratings. Compressed air versions offer up to 13bar.
