The RCD300M2 residual current relay is designed to provide sensitive ground fault protection without the problems associated with high-sensitivity nuisance tripping. It operates continuously and has the unique feature of a metering output to drive either a remote meter or interface with a PLC. By using it, leakages can be seen as they occur and ground faults can be detected before they become critical. The 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.
- Adjustable time delay of 0-1.5 sec adapts to unique applications.
- Metering output with PLC interface for ease of continuous monitoring of system.
- Transformer continuity test allows immediate assurance of a safe system.
- C.T. Loop Monitoring.
- Harmonic Filtering.
- DIN Standard molded case for ease of mounting via snap on rail or screw mounting.
