The invention discloses a voltage and current protection device for a communication device. The voltage and current protection device comprises a shell and a plug, an overvoltage protector, an overcurrent protector and an alarm are arranged in the shell in one time, the overvoltage protector comprises a gas discharge tube and an overvoltage grounding device, the overvoltage grounding device comprises a sleeve, a fusible sheet and a signal rod; the overcurrent protector comprises a hot coil and an overcurrent grounding device; and the alarm is arranged at the top of the shell. The overvoltage grounding device is added into the overcurrent protector to allow the grounding to be more reliable when overload occurs and prevent the discharge tube from being damaged. The overcurrent grounding device is changed to be grounded at front of a hot-wire coil so as to prevent the hot-wire coil from being damaged when overload occurs.
