POWR-GARD® Ground Fault Relays
Lead Free Status / RoHS Status
Lead free / RoHS Compliant
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. This output signal gives
the RCD300M2 both protective and predictive
capabilities. 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.
The RCD300M2 can operate on grounded, high-
resistance grounded and ungrounded power
systems. When a ground fault occurs, the
RCD300M2 operates the leakage current output
relay after the preset time delay. The
RCD300M2 also continuously checks the
connection to the C.T. If the C.T. circuit is
broken, the RCD300M2 indicates "C.T. Fault"
and operates the output relay. Due to its
sensitivity, the RCD300M2 provides a high
degree of network protection and personnel
safety as well as minimizing the risk of fire.

Applications
Ground fault relays can be used for the protection of
critical circuits in applications such as panel boards
and switch boards, OEM power distribution panels
and custom controls. Additional applications include
electric vehicle charging systems, wastewater
treatment plants, marinas, pools and spas.
Maintenance
The RCD300M2 requires no special maintenance
procedures. Regular operation of the test features at
suitable intervals and cleaning of the external parts
are sufficient.
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.
