7EATON CORPORATION BR003010ENNow, there is finally a protective device that can recognize micro-lightning by “listening in“ to the wire. Unlike in short-circuits and earth fault cases, the occurrence of an arc fault still leads to and permits the flow of a normal operating current making its detection more difficult and requiring technical finesse. Of course, arc fault detection alone cannot protect against all hazards such as short-circuits, overcurrent and earth faults. Therefore, it is reasonable to combine arc detection with circuit breakers and residual current devices in order to fully minimise the risk of electrically caused fires.Comprehensive protection to reduce fire hazardsComplete protectionEARTH FAULTdetected viatoroidal transformerSERIAL & PARALLELARC FAULTdigital arc fault detectionSHORT-CIRCUIT &OVERCURRENTthermal andmagneticdetectionRCDMCBAFDD
