LINETRAXX® SmartDetect MRCD410R

Response range from 10 mA to 30 A
Potentiometers for setting the most important parameters directly on the device
NFC interface for easy configuration with the Bender Connect app
Modbus RTU interface for reading out measured values and parameterising the device
Compact design, only 18 mm wide.

Modular residual current devices of type MRCD410R are designed for AC and pulsed DC residual and fault current measurement in earthed TN and TT networks. The devices can
be used as an additional protective measure for the following protection goals, among others:

Protection against indirect contact (DIN VDE 0100-410, IEC60364-4-41)
Protection against thermal effects (DIN VDE 0100-420, IEC60364-4-42)
System protection (DIN VDE 0100-430, IEC60364-4-43)

A modular fault current device according to product standard IEC 60947-21 Annex M is completed by a measuring current transformer designed for this purpose and a circuit breaker with undervoltage release (device combination).
Suitable measuring current transformers are listed in the technical data. The switching time of the circuit breaker with undervoltage release incl. tripping device under load must not exceed 20 ms.

Applications

For the installation of a (fault current) protective device as an (additional) protective measure within the scope of the protection objectives for personal, fire and system protection.
Generally as an alternative to conventional RCDs at higher voltages and currents, possible false tripping of these RCDs, as well as flexible adaptation to the system conditions.
