Automatic circuit breaker market is expected to witness considerable growth in the coming years due to increasing safety concerns across several sectors such as electronic, telecommunication, electrical and automotive. With the installation of smart grid infrastructure, the need of automatic circuit breaker increases. Automatic circuit breakers can also be deployed as super grid or micro grids, which can carry high volume of electricity over long distances.
Automatic circuit breaker is a protective device designed to stop the flow of electric current during overloading and over-stressed circuit conditions. Automatic circuit breakers generally open up the electric circuit on sensing a damage or faulty situation. Over current and short circuit are the types of protection provided by automatic circuit breaker. Unlike an electric fuse, which needs manual work, automatic circuit breakers can be reset either manually or automatically to resume normal operation. Power transmission over long distances requires automatic circuit breakers for higher capacity of faultless transmission, due to which power transmission sector stands as the largest consumer for automatic circuit breaker market. Automatic circuit breakers are available in varying sizes depending on their application area such as homes, small scale industries and others.
Conventional transmission power lines are being upgraded to high voltage direct current (HVDC) lines and high voltage alternating current (HVAC). High voltage lines offer various advantages over low voltage lines; such as low electrical loss and less expensive. Automatic circuit breaker is generally used to halt or slow down the overloading condition, thereby reducing the damage that may cause in high voltage lines.
Based on voltage class, automatic circuit breaker market can be classified as low voltage circuit breaker, medium voltage circuit breaker (air circuit breaker, vacuum circuit breaker and others), and high voltage circuit breaker. Based on structure, automatic circuit breaker market can be categorized as interrupting type, construction type and others. Irrespective of their category, circuit breakers can be used across multiple sectors, including residential and non-residential building constructions, non-automotive transportation equipment and electronic equipment, automotive and electrical equipment.
Demand for low voltage switchgear circuit breakers is expected to increase during the forecast period, due various reasons including global development in industrial infrastructure, safety enhancement, and product innovation. One of the major factors contributing to the growth of circuit breaker market is initiative to replace old and outworn power infrastructure with high grid power infrastructure.
