Hi, I'm working on an electric car project and need to choose a DC contactor to use with a emergency shutdown switch. The one I am looking at has the datasheet here (product number: 70-902):
http://www.farnell.com/datasheets/1...2.1454877608.1561455759-1420353443.1560869731
I am dealing with a peak current of 60 A and a 48 V nominal (54 V peak) battery voltage. In the datasheet, under "contact rating" the voltage specified is the same as the coil voltage (12 V) which seemed low to me when I bought it, and I thought that this value was actually the coil voltage under these max current conditions as underneath, the "breakdown voltage" is 500 Vrms at 60 Hz. However I am now not sure what to think and maybe the rated contact voltage actually is 12 V and the "breakdown voltage" is the max voltage once the circuit is open. Could someone clarify what this means? Thanks a lot!
