Load break switch refers to a disconnect switch whose function is to make or break the electrical connection at certain specified levels of current. A load break switch is generally used for medium voltage level systems for the purpose of switching and protection. In simpler terms, a load break switch is designed to cut off the healthy circuits or to disconnect the load in case of any faults or for maintenance purpose. As a safety measure, load break switches are turned on under no-load conditions. Hence, it has no making capacity unlike the Circuit Breaker which are designed to operate under abnormal conditions such as overcurrent or transients, in order to clear the fault and isolate the electrical system and the connected load.
In some cases, load break switches can be supplied with additional equipment in order to provide a limited load switching capability. Additionally, an air gap switch can be modified by connecting them with a series interrupter for making them capable of operating at high voltage and current levels. The series interrupters significantly increase the load break capabilities of the disconnect switch and hence, it can be used switching load or fault currents of the associated equipment.
