AC/DC sensitive residual current monitoring module with integrated divisible measuring current transformer

AC/DC sensitive residual current monitoring module with integrated divisible measuring current transformer Product description The RCMB330 residual current monitoring modules are intended for measuring AC and DC fault currents in earthed systems (TN and TT systems). The modules are able to measure residual currents IΔ = 10…500 mA in a frequency range of DC…100 kHz. Two separately adjustable response values allow a distinction to be made between prewarning and main alarm. The modules feature an RS-485 interface with Modbus RTU which can be used to transfer measured values and alarm values. Setting...

AC/DC sensitive residual current monitoring module LINETRAXX® RCMB330 Device view RCMB330 Installation instructions • Do not route any shielded cables through the measuring current transformer! • Device damage due to interference pulses! The connecting cable (supply, analogue interface...) must not be routed directly past the current transformer core/primary conductor. No. Element Description 1 Unlock current Press both elements together simultaneously transformer core and flip the RCMB330 open For manual test, manual reset, degaussing, offset calibration (use pointed object to press) The cable...
