WebThe RCD300M2 operates in conjunction with a Littelfuse WKE Series current transformer. The combination of the RCD300M2 measuring signal and the output signal from the WKE provide the required resilience to electrical noise - the main cause of nuisance tripping. Features/Benefits. Adjustable sensitivity of 10 mA to 3.0 A reduces nuisance trips. WebResidual current devices are obliged to make and break the current of value at least 10 I n or 500 A, whichever is the greater. This ability is required for RCDs without backup protection by overcurrent protection devices. During the test, current of value equal to 500 A flows through the main terminals of the RCD and then residual current 10I Δn is forced … conyers office depot
