Externally Fused – For this type of connection, each fuse unit is connected externally to the capacitor bank. This helps to save the capacitor bank from faults like surge voltage, temperature, etc. without any interruption in the operation. Internally Fused – In this type, the fuse is kept inside the casing of the capacitor bank.
