Product Description
Argus-7SR10
The Siemens Reyrolle 7SR10 Argus is a numerical overcurrent and earth fault relay designed as a cost-effective solution for distribution and industrial applications. It provides reliable protection, monitoring, instrumentation, and metering in power systems. The relay integrates the latest hardware technology and is available in multiple configurations based on power supply, binary input/output options, and communication capabilities.
Key Features and Specifications:
- Versatile Power Supply: The 7SR10 supports a universal power supply, making it compatible with both AC and DC power sources.
- Multiple Variants: Available in different configurations (7SR1003 for current protection, 7SR1004 with additional voltage inputs, and 7SR1005 for motor protection).
- 1A and 5A CT Selectable: The current transformer (CT) setting can be selected on-site for flexibility.
- Communication Protocols: The relay supports MODBUS RTU and IEC 103 communication protocols, both of which are site-selectable.
- DI/DO Configuration: It includes up to 6 Digital Inputs (DI) and 6 Digital Outputs (DO) for comprehensive monitoring and control.
Housing and Accessibility:
- The relay is housed in a 4U high, size 4 non-draw-out case.
- Front USB port for local connection to a PC.
- Rear RS485 port (optional) for remote communication access.
Protection Functions:
The 7SR10 offers a wide range of protection features, including:
- Broken Conductor/Load Unbalance (46BC)
- Negative Phase Sequence Overcurrent (46NPS)
- Thermal Overload (49)
- Instantaneous Overcurrent Protection (50)
- Instantaneous Earth Fault Protection (50N/G)
- Time Delayed Overcurrent Protection (51)
- Time Delayed Earth Fault Protection (51N/G)
- Cold Load Pickup (51C)
- Circuit Breaker Fail (50BF)
- Time Delayed Sensitive Earth Fault Protection (51SEF)
- Inrush Restraint (81HBL2)
- Instantaneous Sensitive Earth Fault (50SEF)
Supervision Functions:
- Trip Circuit Supervision (74TC): Monitors the trip circuit status.
- Total Harmonic Distortion Supervision (81THD): Ensures system integrity by supervising harmonic distortions.
