As the voltage increases, an inrush of current flows into the uncharged capacitors. Inrush current can also be generated when a capacitive load is switched onto a power rail and must be charged to that voltage level. The amount of inrush current into the capacitors is determined by the slope of the voltage ramp as described in
High inrush current affects the source power supply. Often high inrush current drops the source voltage and results in a brownout reset for microcontroller-based circuitry. In few cases the amount of current supplied to the circuit gets beyond the acceptable maximum voltage of the load circuit, causing permanent damage to the load.
An inrush current limiter circuit limits the input current and keeps the source and the host device safer. Because a high inrush current increases the failure chances of the circuit and that needs to be rejected. Inrush current is harmful because of the following reasons- High inrush current affects the source power supply.

Abstract: When a circuit breaker switches on high voltage shunt capacitors, high inrush current will occur and may induce restrike, which will harm the power system and some electrical devices.
When power is initially applied to the system, charging these capacitors can result in an inrush current which can exceed the nominal load current. If left unaddressed, this can cause voltage rails to fall out of regulation, resulting in the system entering an undesired state.
