Application
ZJ800A DC Contactor 24V/48V means the load rated current is 800A, silver alloy contacts, the voltage marked on the contactor nameplate refers to the rated voltage that the main contact can withstand.
Ordering Notice
For example: ZJ800A/12V
The DC contactor of main contact is one NO, rated voltage not more than DC 48V, current 800A, coil
