Siemens 3UG5 Series Monitoring Relay, 5A Maximum Current Sensed, 200/690V AC Supply AC Voltage - 3UG5512-1BR20
This monitoring relay provides continuous supervision of three-phase supplies to detect phase sequence irregularities, phase loss and voltage asymmetry in industrial control installations. Designed for panel mounting on a 35mm DIN rail, it monitors AC supply voltages across a wide frequency range and offers LED indication for status, making it suitable for automated and electrical systems where phase integrity is required.
Features & Benefits
• Detects phase sequence and failure enabling Rapid fault identification
• Monitors asymmetry with indirect voltage-limit checking protecting motors
• Supply range 200–690 V AC supporting varied industrial networks
• DPDT output contacts rated 3A delivering robust switching capability
• Response buffering 20ms to maintain monitoring during brief interruptions
• Thermal operating range −25 to +60 °C allowing broad environmental use
• Monitors asymmetry with indirect voltage-limit checking protecting motors
• Supply range 200–690 V AC supporting varied industrial networks
• DPDT output contacts rated 3A delivering robust switching capability
• Response buffering 20ms to maintain monitoring during brief interruptions
• Thermal operating range −25 to +60 °C allowing broad environmental use
**Applications**
• Suitable for protecting three-phase motors from phase loss and reversal
• Ideal for integration in motor control centres and distribution panels
• Used for supervising three-phase supply integrity in automation systems
• Can be used for preventative maintenance monitoring of plant power supplies

What contact material and configuration are provided for switching?
The outputs use AgSnO2 contacts in a double-throw arrangement with two changeover contacts for auxiliary switching needs.
How should conductors be terminated to ensure secure connections?
Screw terminals accept solid or finely stranded conductors from 0.5 to 4 mm² and require a stripped length of 10mm with 0.6 to 0.8 N·m tightening torque.
What electrical isolation is present between circuits?
There is galvanic separation between input and output circuits as well as between the outputs and the supply, ensuring segregated signal paths.
How does it perform under electromagnetic disturbance?
It meets EMC criteria with immunity to bursts, surges and ESD at levels specified for industrial environments and complies with IEC interference standards.
Are there any short-circuit protection recommendations for the relay outputs?
Use gL/gG fuses rated 6 A or an MCB type C rated 1A for protecting both normally open and normally closed relay contacts.
