The 12 x 13.3mm device is one of two members of the 871 fuse series, the other is rated at 150A.
The full part numbers are:
- 0871200.UR 200A, 240mΩ, 90mV nominal voltage drop
- 0871150.UR 150A, 300mΩ, 75mV nominal voltage drop
These are nominally fast-acting, and are rated to operate over -55 to +100°C.
Interrupt rating for both is 1.5kA at 75Vdc – nominal melting at this current is 40500A2s, or 21500A2s for the 150A part.
Temperature rise is very dependent on the installation. The company gives an example of 114°C rise at 200A on a thick PCB with thick (15oz, 525μm) copper – see the data sheet for caveats and more.
