It features an adjustable current range of 0.1 to 10A and a wide supply voltage range of 24-240V AC/DC. Equipped with an adjustable delay time of 0.1 to 20 seconds, this relay ensures reliable protection against overcurrent or undercurrent conditions in electrical circuits, providing essential monitoring functionality for various industrial applications.

## Long description

The Siemens SIRIUS 3UG4622-1AW30 is a high-precision digital single-phase current monitoring relay engineered for demanding industrial automation environments. This device provides continuous oversight of electrical circuits, ensuring that current levels remain within predefined thresholds to prevent equipment damage or process interruptions. With its versatile design, it supports a wide supply voltage range and offers flexible configuration options to suit diverse operational requirements.
Advantages
This monitoring relay stands out due to its digital precision, which allows for accurate threshold settings and reliable performance in complex electrical systems. The wide supply voltage range of 24-240V AC/DC enhances its compatibility across various global power standards, reducing the need for multiple device types in a single facility. Furthermore, the adjustable delay time feature helps prevent nuisance tripping caused by temporary current spikes, ensuring stable and consistent monitoring of critical machinery.
Suitable for
Monitoring motor current to detect mechanical overload
Protecting heating elements from overcurrent conditions
Supervising pump systems for dry-running or blockage detection
General industrial automation and control cabinet applications
When it may not be suitable
This device is designed specifically for single-phase monitoring and cannot be used for three-phase current supervision. It is also not intended for high-voltage power distribution networks exceeding its specified operational limits.
Key specifications
Current monitoring range: 0.1 to 10A
Supply voltage: 24-240V AC/DC
Adjustable delay time: 0.1 to 20 seconds
Monitoring type: Single-phase current
Digital display and configuration interface
How to use
Installation should be performed by qualified personnel in accordance with local electrical safety standards. The relay is designed for standard DIN rail mounting within a control cabinet. Once mounted, connect the supply voltage to the designated terminals and wire the monitored current circuit through the device. Use the integrated digital interface to set the desired current thresholds and the required time delay. After configuration, the relay will automatically monitor the circuit and trigger the output contact if the current deviates from the set parameters.
What to consider before purchase
Ensure the current range of 0.1-10A is sufficient for your specific application load.
Verify that the control cabinet environment meets the required temperature and humidity specifications.
Confirm that the single-phase monitoring capability aligns with your circuit architecture.
Usage recommendations
Regularly test the relay functionality during scheduled maintenance intervals to ensure that the trip thresholds remain accurate and the output contacts are operating correctly.
