The EKM8 series of thermal magnetic fixed molded case circuit breakers are designed for use in power distribution networks operating at AC 50/60Hz. They have a rated insulation voltage of 1000V and a rated operating voltage of 400V or lower. These circuit breakers can handle a rated current of up to 2000A, making them ideal for distributing electric energy and protecting lines and power equipment from damage caused by faults such as overload, short circuit, and under voltage. Additionally, circuit breakers with a rated current of 630A or lower can also be used to provide motor protection. In normal circumstances, these circuit breakers can be used for infrequent circuit switching and motor starting.
