terminal).
3. Basic parameters
Nominal voltage: 12V;
Rated current: DC150A;
Closing voltage: ≥ DC7V;
Released voltage: ≤ DC4.5V;
Contact voltage drop: below 0.2V (at 150A);
Coil current: below 3.5A.
4. Possible failures
The coil or lug is open and the contact cannot be absorbed.
Short circuit of the coil, causing failure in the contact point pulling in;
Corroded or ablated contact point, causing failure in connection even if it is closed;
Contacts that cannot be disconnected caused by excessive current;
Open circuit of power circuit (power pole B, coil terminal) , causing the whole vehicle
unable to start.
