A refrigerant compressor includes an electric motor. A current sensor measures current to the electric motor. A switching device is configured to close and open to allow and prevent current flow to the electric motor, respectively. A maximum continuous current (MCC) device generates an output that one of: (i) is an MCC for the electric motor and (ii) is a value indicative of the MCC for the electric motor. A motor protection module: is remote from the MCC device; receives the output wirelessly from the MCC device via an antenna; one of sets a first MCC to the MCC for the electric motor and determines the first MCC based on the value indicative of the MCC for the electric motor; selectively sets a predetermined MCC to the first MCC; and controls the switching device based on a comparison of the current to the electric motor and the predetermined MCC.
