What is the Schleicher SIW1003 (A) Line Monitoring Relay?
The Schleicher SIW1003 (A) is a line monitoring relay employed within industrial electrical circuits for monitoring power quality and avoiding machine damage caused by abnormal voltage conditions. Being compact and highly sensitive, it serves as a vital component in automation panels, particularly in those environments where uptime and accuracy cannot be compromised.
It monitors continuously:
- Phase loss
- Phase sequence
- Voltage imbalance
- Under/Over voltage detection
The instant an anomaly is registered, the relay reacts by triggering a signal to the control system to avoid equipment breakdown or system-wide failures.
Major Features
Three-phase monitoring with extended protection
- Automatic or manual reset features
- LED lights for rapid status checking
- DIN rail mounting for convenient installation
- Large voltage range to accommodate varied systems
- Compact and durable design for demanding industrial settings
Applications
This relay is an essential element in:
- Industrial control panels
- Marine power distribution boards
- HVAC systems
- Elevator control systems
- Compressors and pumps
In marine applications, where stable voltage control is crucial to navigation and onboard equipment, the Schleicher SIW1003 (A) guarantees seamless power quality.
As an example, in marine control systems, this relay can be fitted alongside Contactor units to provide safe start/stop functionality in motor-driven machinery.
