Application
The Argus is a numerical overcurrent protection relay
intended for use on distribution and industrial networks. It
provides a highly comprehensive functional software
package with a range of integral application functions aimed
at reducing installation, wiring and engineering time.
An extensive range of metered values can be viewed on the
front LCD or at a remote point via the communication
channel.
The integrated control feature allows operation of a single
circuit breaker and monitoring of its trip and close circuits.
