Summary:PURPOSE: An underground low pressure distribution box using CDMA for supplying the convenience of administration is provided to accurately recognize a remote monitoring underground low-voltage distribution box through CDMA. CONSTITUTION: A breaker operating status detector detects the operation state of a breaker. The current detector detects the current amount according to phase of the alternating current source supply line. A multiplexer(103) selects the supply voltage according to each load. A microprocessor controls the gathering of the current sense result and breaker operation state, and the remote transmission. A CDMA(Code Division Multiple Access) modem transmits state detection data through the CDMA communications in the remote.
