Broad range of monitoring relays to control voltage and current from Selec
The relays are monitoring the setpoint values and are signalising the over- or underexceedence of the preset values. Depending on the version the units have one or two changeover contacts.
The monitoring relays are mounted on a 35mm DIN rail.
Digital one- or triphase AC voltage monitor with or without neutral. Signalises overvoltage, undervoltage, overfrequency, underfrequency, phase loss, phase asymmetry and phase sequence.
Digital single phase AC current monitoring relay. Monitors over- and uncercurrent, up to 5A direct connection, over 5A connection with external current transformer.
Digital three phase AC current monitoring relay. Monitors over- uncercurrent and asymmetry, up to 5A direct connection, over 5A connection with external current transformers.
