Digital relay / security / overload / overcurrent - 7SJ600

The SIPROTEC 7SJ600 is a numerical overcurrent relay which, in addition to its primary use in radial distribution networks and motor protection, can also be employed as backup for feeder, transformer and generator differential protection.
The SIPROTEC 7SJ600 provides definite-time and inverse-time overcurrent protection along with overload and negative-sequence protection for a very comprehensive relay package. In this way, equipment such as motors can be protected against asymmetric and excessive loading. Asymmetric short-circuits with currents that can be smaller than the largest possible load currents or phase interruptions are reliably detected.

Digital relay / security / electrical line - 7ST61, 7ST63

The numerical overhead contact line protection relay Siprotec 7ST61 / 7ST63 is a selective and quick responding protection device for overhead contact lines fed from one or multiple points in AC traction power supplies.

The relay possesses all functions required to protect a section of the overhead contact line and can therefore be deployed universally.
The Siprotec 7ST61 / 7ST63 numerical overhead contact line protection relay is a member of the Siprotec 4 product family, which stands for excellent quality and powerful protection relays and is characterized by the following features:
Powerful 32-bit microprocessor system
Completely numerical data processing and control, from the measurement of voltages and currents to the switching decision logic of the circuit-breaker
Complete galvanic and interference-immune isolation of the internal processing circuitry from the measurement, control and power supply circuits of the switchgear via measured value trans formers, binary input and output modules, and DC and AC voltage converters
Simple operation via integrated operator panel or connected personal computer with operating software Digsi 4
Storage of fault indications and instantaneous values for fault recording

Digital relay / security / overcurrent - 7SJ601

The Siprotec 7SJ601 is an overcurrent relay that may be used to protect a motor. It also works for line, transformer and generator controls. This is useful for managing definite-time and inverse-time currents and will protect all units.

Digital relay / security / frequency / over-excitation - 7RW600

The SIPROTEC 7RW600 is a numerical multifunction protection relay for connection to voltage transformers. It can be used in distribution systems, on transformers and for electrical machines. If the SIPROTEC 7RW600 detects...

Digital relay / security / frequency / over-excitation - 7RW600

The SIPROTEC 7RW600 is a numerical multifunction protection relay for connection to voltage transformers. It can be used in distribution systems, on transformers and for electrical machines. If the SIPROTEC 7RW600 detects any deviation from the permitted voltage, frequency or overexcitation values, it will respond according to the values set. The SIPROTEC 7RW600 can be used for the purposes of system decoupling and for load shedding if ever there is a risk of a system collapse as a result of inadmissibly large frequency drops. Voltage and frequency thresholds can also be monitored.

The SIPROTEC 7RW600 voltage, frequency and overexcitation relay can be used to protect generators and transformers in the event of defective voltage control, of defective frequency control, or of full load rejection, or furthermore islanding generation systems.

Digital relay / control / small / air conditioning - CL series

CL range logic relays are suitable for small and medium-sized control tasks and are able to substitute logic wiring in a quick and simple manner.
They can be used for applications in control as well as for timing functions, e. g. in buildings, lighting systems, air-conditioning systems, general control functions or in small machines and systems or as stand-alone control module for small applications.

Steps to the application of CL logic relays
CL logic relay can be used easily, rapidly and comfortably without any time-consuming planning and programming. The user can discover the advantages and the benefit of these logic relays in no time at all. The CL logic relays provides for the control statements according to a simple circuit diagram. Setup, storage, simulation and documentation are performed using the compact and user-friendly CL-SOFT software (CL-LAS.PS002).
