-30V/+30V protection
&quot;So, if possible, no fuse&quot;
Fuses protect from over current faults.
For your over voltage protection I suggest you to use bidirectional TVS diodes.
Bidirectional TVS diodes are always symmetric. Example +/- 30 V or +/- 24V
They protect your circuitry from temporary over voltage faults.
I've using for years NXP's PESD1CAN devices.
