Multi-channel AC, pulsed DC and universal AC/DC sensitive residual current monitoring system RCMS460

General description:
Monitoring system for AC, pulsed DC and AC/DC current to monitor residual currents, fault currents and operating currents in earthed AC, DC and AC/DC systems (TN and TT systems). To increase operational and plant safety, and reduce the risk of fire, in particular with regard to IEC 61008, EN 61008, DIN VDE 0664; Draft E DIN IEC 64/1134/CD, DIN VDE 0100 part 540; IEC 60364-4-44, DIN VDE 0100-444; IEC 60364-5-548, DIN VDE 0800-2-548 and Safety and Health Protection according to EU Directives 95/63/EC, 1999/92/EC, 2001/45/EC. Remote parameterisation and display are possible through a personal computer (standard web browser) by means of a COMTRAXX gateway (e.g. COM460IP or CP700). 

Residual current evaluator RCMS460-L: 
Twelve-channel evaluator for the monitoring of residual currents, fault currents and operating currents in earthed AC, DC and AC/DC systems (TN and TT systems) in connection with measuring current transformers. AC, pulsed DC or AC/DC current measuring function is specified by selecting the relevant measuring current transformer, corresponding to type A or B according to IEC 60755. Connection of a standard -/5 A or -/1 A current transformer is possible (via additional CT).

Current measurement as a true r.m.s. value. Monitoring of up to 1080 subcircuits, response time for all channels max. 180 ms. The response values can be set separately for each channel (over- or undercurrent function). Additional pre-warning function (10...100 %) possible. Filter function for protection of persons and units and against fire. Alarm messages: LED per channel and two common alarm relays. 

Parameterisation, display and visualisation are possible by means of a COMTRAXX gateway (e.g. COM460IP or CP700) or RCMS460/490-D.

Sealable enclosure (6 modules) for installation into standard distribution panels in accordance with DIN 43871 and also for DIN rail mounting in accordance with DIN EN 60715 or screw mounting.
