Littelfuse, Inc. 30V 10A ADR Time Delay Relay with 24V Coil 05931400

This 30V 10A ADR Time Delay Relay with 24V Coil (05931400) is an off-delay timer that is 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 a urea chemical agent. 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 an off-delay timer relay that delays the isolation of the batteries.
