Since the discovery of energy, safety has been a paramount subject matter. This, we can see in today's electrical systems where protective devices such as fuse and circuit breakers are used to prevent fire hazards resulting from overload, overvoltage and short circuits. However, with all the revolution in technology, these options may be considered less smart since the fuse, made with wire strands calculated for specific current capacity faults permanently when the specified current rating is exceeded. While the circuit breaker which is made up of mechanical switch fails as a result of carbon forming and the wearing away of the contacts because of arcing. As a means of improvement, this paper presents the design and development of an automatic single phase protective device using solid state relay (SSR). This study is to ensure automatic cut off from power supply in cases of overvoltage (above 240 V AC) or when overload and short circuit (current above 8amps) is detected without permanent damage of a fuse placed along current path. Also the design will ensure that there is an automatic close circuit whenever the trigger switch is (momentary switch) is closed. The system is achieved via the use of PIC micro-controller, current sensor and other discrete components. The system is tested and works well inhibiting the frequent faulting of fuses. It also helps to prevent hazard as a result of overvoltage, overload and short circuit and ensures a close circuit when the trigger switch is closed.
