RCM410R

Product catalog summary

Device Overview
The LINETRAXX® RCM410R is a single-channel residual current monitoring device designed for AC systems, sensitive to both AC and pulsed DC currents. It complies with DIN EN IEC 62020-1, Type A standards, and is suitable for preventive maintenance in TN, TT, and IT systems.

Key Features

RMS measurement with a residual operating current range of 10 mA to 30 A.
Prewarning capability at 50-100% of the residual operating current.
Supply voltage options: DC 24 V or AC/DC 100-240 V (RCM410R-2).
LED-strip for measured value display and adjustable response delay.
Alarm relay with selectable N/C or N/O operation and fault memory behavior.
RS-485 with Modbus RTU and NFC interface for parameter setting.

Intended Use
The RCM410R is intended for use with specified measuring current transformers for monitoring residual currents in AC systems. It is designed for installation in control cabinets or protected environments.

Functional Description
Upon applying supply voltage, the device undergoes a start-up delay. Residual current detection is performed via an external current transformer. Alarms are triggered if the measured value exceeds set thresholds, with options for prewarning and main alarms.

Technical Specifications

Insulation coordination: Rated voltage of 250 V, overvoltage category III.
Supply voltage: DC 24 V or AC/DC 100-240 V with specific tolerances.
Measuring circuit: Frequency range of 42-70 Hz, with a measuring range of 2 mA to 70 A peak.
Time response: Configurable start-up delay, response delay, and release delay.
RS-485 interface: Modbus RTU protocol with a maximum baud rate of 115.2 kbits/s.

Environmental and Mechanical Conditions

Operating temperature: -25 to +55 °C.
Protection degree: IP20 for terminals, IP30 for internal components.
Mounting: Vertical on DIN rail.

Approvals and Standards
The device complies with standards such as DIN EN IEC 62020-1, UL508, and UL1053. It also meets the requirements of the Radio Equipment Directive 2014/53/EU.

Ordering Information
Available in two models: RCM410R-24 (DC 24 V) and RCM410R-2 (DC 24 V, AC/DC 100-240 V). Accessories include a sealable transparent cover.

Dimension diagrams The NFC interface can be used to transmit a previously configured device parameter setting directly to the device. This function is available only via the Bender Connect App. You can find this app in the Appstores for iOS and Android. In the Bender Connect app the device first needs to be made known. Then the device-specific setting options are shown so that they can be configured. When the data is transferred, feedback is given whether the parameter configuration has been successful. Parameter settings can be transmitted to the device via the Bender Connect app by holding...
