Claim 0:
1. An electronic circuit breaker, comprising:
a circuit breaker;
a circuit board including:
a wireless communication circuit including
a plurality of antennas configured to receive a control signal, the antennas including cellular, digital cellular network, wireless networking and dual-mode low range antennas;
a power amplifier;
a low-noise receive amplifier;
a plurality of frequency filters;
receiving and transmitting circuitry;

a microprocessor connected to the wireless communication circuit and configured to receive the control signal and generate a trigger signal;
a power supply circuit connected to the microprocessor, the power supply circuit including a first capacitor and a second capacitor;
a relay circuit connected to the power supply circuit, wherein the relay circuit is configured to receive the trigger signal from the microprocessor and turn the circuit breaker ON or OFF based on the control signal,
wherein the relay circuit comprises
a first resistor connected to the microprocessor at a trigger signal pin;
a transistor having a gate connected to the first resistor, the gate configured to receive a trigger signal which turns the transistor ON or OFF;
a reverse biased diode connected between a power source and a collector of the transistor;
aground connected to an emitter of the transistor;
a transformer connected in parallel with the reverse biased diode, the transformer configured to generate a magnetic field when the transistor switch is ON; and
a magnetic contactor circuit configured to switch a contactor between ON, OFF and neutral states in response to the magnetic field.
