摘要： An electronic fuse (506, 507) suitable for use in a direct current, DC, applications which is exposed to surges. The electronic fuse (506,507) comprises a current sensor (500) for measuring a current flowing in a current path of the DC system, the electronic fuse comprising a first transistor switch (501) which is arranged in the current path, the first transistor switch comprising at least one parasitic diode (511) having a forward direction which is opposite to an operational DC direction of the current path. The electronic fuse further comprising a controller (502) operatively connected to the current sensor (500) and adapted to control the first transistor switch (501) based on the measured current, and a current restrictor (503,520) which is capable of blocking a current from flowing in the current path in a direction opposite to the operational DC direction.
