Brief:Arc fault circuit breakers are also known as arc fault inspection devices. AFDD is mainly to reduce the risk of electrical fire caused by series arc or parallel arc faults between live conductors. , It can check the electric arc fault, disconnect the power circuit before the electric fire occurs, and effectively avoid the electric fire caused by the arc fault. AFDD can also be combined with residual current protection appliances and overcurrent protection appliances to form a multi-purpose protection device.
Brief:• Accurately judge normal arc and fault arc. • With RS-485 communication interface, it can communicate with the electrical fire monitoring equipment in the fire control room through • Modbus-RTU communication protocol, and can realize remote monitoring. • When a fault arc is detected, the alarm output contact will send an alarm signal to the monitoring device. • The residual current alarm function can be added.
