RCM, Residual Current Monitors

1.AcuRC 410 Residual Current Monitors 2.Early warning selectable 3.External Current Transformer

Introduction

The residual current monitors (RCMs) AcuRC 410 series continuously monitor the level of the residual current in earthed system (TN and TT systems), according to the standard of IEC62020, IEC60755, IEC60364. The devices are intended to be used in AC systems. Both single-phase and three-phase systems can be monitored. They can also be used for current monitoring of single conductors, which in normal operation carry no current, such as PE, Nconductors. In addition, AcuRC 412 measures line voltage or phase voltage, while AcuRC 413 measures temperature. The AcuRC 410 series monitor, with four keys and LCD display, is convenient for you to get all the parameters of residual current. The parameters can also be centralized on a PC or PLC through RS485 link using MODBUS protocol.
