LINETRAXX® RCMS460-D/-L – RCMS490-D/-L - 2

Multi-channel AC, pulsed DC and AC/DC sensitive residual current monitors for earthed AC, DC and AC/DC systems (TN and TT systems) Product description RCMS460-D…/-L… and RCMS490-D…/-L… The RCMS system consists of one or more RCMS460-D/-L or RCMS490-D/-L residual current monitors, which are able to detect and evaluate fault, residual and operating currents in earthed power supplies via the related measuring current transformers. The maximum voltage of the system to be monitored depends on the nominal insulation voltage of the measuring current transformer used in the case of busbar systems,...

LINETRAXX® RCMS460-D/-L – RCMS490-D/-L - 3

Residual current monitors LINETRAXX® RCMS460-D/-L – RCMS490-D/-L Digital input Each individual channel can be used for one of the following monitoring functions: – s digital input using a potential-free contact 1/0 A – r for current or residual current monitoring in combination O with measuring current transformers. History memory in RCMS460-D, RCMS490-D The device utilises a history memory for failsafe storing of up to 300 data records (date, time, channel, event code, measured value), so that all data about an outgoing circuit or an area can be traced back at any time (what happened...
