CME420 |
 Digital current relay for AC systems (true RMS)
|
|
The CME420 series monitors for undercurrent and overcurrent in AC systems, as well as the current between two threshold values (window discriminator function). The currents are measured as true AC RMS values. The current value is dynamically displayed on the digital LCD screen. Alarm trip values are stored into memory. Current measurement is possible either indirectly or directly via standard current transformers (x/5 A). An external supply voltage is required.

CSE140 |
Undercurrent relay for AC systems
|
|
The CSE140 series monitors detect undercurrent in AC systems. The response value, response delay, and hysteresis are set via potentiometers. External supply voltage is required.

CSE141 |
Overcurrent relay for AC systems
|
|
The CSE141 series monitors detect overcurrent in AC systems. The response value, response delay, and hysteresis are set via potentiometers. External supply voltage is required.

CSD200 |
Overcurrent relay for three-phase AC systems
|
|
The CSD20X series monitors for overcurrent in three-phase systems. Measurements are taken directly and indirectly with measuring current transformers. External supply voltage is required.

CSD230 |
Overcurrent relay for three-phase AC systems
|
|
The CSD23X series monitors for overcurrent in three-phase systems. Measurements are taken directly and indirectly via measuring current transformers. External supply voltage is required.

CSG140 |
Undercurrent relay for DC systems
|
|
The CSG140 series monitors for undercurrent in DC systems. The current is measured either directly or by means of a shunt. The response value, response delay, and hysteresis are set via potentiometers. External supply voltage is required.
