Does anyone have the typical ON hold current for the high-current Bosch 

relays such as Bosch p/n 0 332 209 150 ?


	




     I don't have that part number but a quick look at the variety

     of beer-can and plastic automotive relays in my stock show that

     at room temperature, they pick up at about 50% of rated and hold

     down to 15-25% of rated voltage. As temperature of relay goes

     up, the hold current will be relatively constant while the hold

     voltage climbs due tempco of copper in the coil.
