The 05931500 is a delay-off timer relay designed to delay the disconnection of the ADR battery switch in commercial vehicles compliant with EURO 4, EURO 5, and later standards, ensuring power remains supplied to the SCR system for a 6-minute cleaning cycle after engine shutdown. It operates at 12V with a continuous current rating of 20A.
These delay-off timer relays are designed to delay the opening of the ADR battery switch installed on vehicles approved for EURO 4 EURO 5 and later. All industrial vehicles produced from 2006+, in order to comply with the pollution regulations, are equipped with the SCR (Selective Catalytic Reduction) system for reducing emissions in exhaust gases using an urea chemical agent (eg. Ad-Blue). This system requires a cleaning cycle of variable life depending on the vehicle, after the engine has been switched off. It is therefore necessary to supply power to the electrical system for about 3 minutes after the vehicle is stopped by installing these relays that delay the isolation of the batteries. Used on ADR trucks approved EURO 4, EURO 5 and later 12V relay with 6 min timer delay
