Title: MC018 120A fuse problem
Post by: macbahi on May 12, 2025, 03:57:42 PM

Hello guys,

From Data sheet MC018 the total current calculation is 160A but the fuse fixed externally is 120A.  Please could you tell me why you use 120A ?  See image.

But if section 60A will used from Logic power so this power pin C1P02 is not sufficient to deliver 60A?  isn't it?


Any way, Is-it necessary to use fuse at Pinout 2 Logic power ?  see image.  If yes what is the value recommended ?

Tanks in advance for your help.

With best regards
Macbahi

Why do you think all output pins can be loaded at max value at the same time?
The high current input terminal and module has a 120A limitation.
