## Summary description

The Siemens 3UG4622-2AW30 is a digital single-phase current monitoring relay designed for precise electrical system protection. It features an adjustable current range of 0.1 to 10A and a wide supply voltage range of 24-240V AC/DC. With an integrated time delay of 0.1 to 20 seconds, this relay ensures reliable monitoring of undercurrent or overcurrent conditions in industrial automation and control applications.

## Long description

The Siemens 3UG4622-2AW30 is a high-precision digital single-phase current monitoring relay engineered to provide robust protection for electrical systems. This device is designed to monitor current levels within a range of 0.1 to 10A, offering flexibility for various industrial applications. It operates on a versatile supply voltage range of 24-240V AC/DC, making it compatible with a wide array of power configurations. The relay includes an adjustable time delay feature ranging from 0.1 to 20 seconds, which helps prevent nuisance tripping caused by transient current spikes.
Advantages
This monitoring relay stands out due to its digital interface, which allows for precise setting of threshold values and clear monitoring of current status. The wide supply voltage range simplifies inventory management and installation, as a single unit can be deployed across different voltage environments. Its compact design ensures efficient use of space in control cabinets, while the integrated time delay function provides enhanced stability by ignoring short-term fluctuations that do not represent actual system faults.
Suitable for
Monitoring undercurrent or overcurrent conditions in motors and pumps
Protection of sensitive electronic equipment in industrial automation
Supervision of heating elements and lighting circuits
General electrical load monitoring in control panels
When it may not be suitable
This device is specifically designed for single-phase monitoring and cannot be used for three-phase systems without additional equipment. It is not intended for high-current applications exceeding the 10A threshold unless used in conjunction with external current transformers.
Key specifications
Current monitoring range: 0.1 to 10A
Supply voltage: 24-240V AC/DC
Adjustable time delay: 0.1 to 20 seconds
Monitoring functions: Undercurrent and overcurrent
Mounting type: DIN rail
How to use
The relay is designed for standard DIN rail mounting within a control cabinet. After mounting, connect the supply voltage to the designated terminals and wire the current circuit to be monitored through the relay inputs. Use the digital interface on the front panel to set the desired current thresholds and the required time delay. Once configured, the device will continuously monitor the current and trigger the output relay if the measured value deviates from the set parameters beyond the configured time delay.
What to consider before purchase
Verify that the load current does not exceed the 10A limit
Ensure the control voltage matches the 24-240V AC/DC range
Confirm that the application requires single-phase monitoring
Check available space on the DIN rail for installation
Usage recommendations
Always ensure that the power supply is disconnected before performing any wiring or configuration changes. Regularly test the relay functionality during scheduled maintenance to ensure the protection parameters remain accurate and the output contacts are operating correctly.
