DSR-6.2 Current Differential Relay
The DSR-6.2 Current Differential Relay is a micro-controller actuated measuring device for protecting three-phase, synchronous, and asynchronous motors or three-phase generators. It captures differential currents and triggers a shutdown when the preset limit values are reached.An advance warning can be issued using a second relay contact. In order to avoid false activations, e.g. when starting large electrical drives, the triggering can be suspended for an adjustable period of time.
The system can reset itself after triggering or advance warning either automatically after an adjustable time period, or via external signal at an input. Expansion options include 2 recorder outputs (1 x 0 ... 10V and 1 x 0(4) ... 20mA).
Upgrades for printout of trigger values and settings are available on request. The DSR-6.2 is available in 5A or 1A variants. Display language options are German or English.
