Siemens 3UG5 Series Monitoring Relay, 200/690V Supply AC Voltage, 5A Maximum Current Sensed - 3UG5514-1BR20
This monitoring relay is a Compact device for three-phase network supervision, designed to detect phase sequence, phase failure, phase asymmetry and undervoltage in industrial AC supplies. It monitors three-phase voltages across a wide range and provides changeover contact outputs for control and protection tasks in automation and electrical installations.
Features & Benefits
• Response delay adjustable 0.1–20 s to prevent nuisance tripping
• Fast buffering time minimum 20ms to bridge brief power interruptions
• Relay contact rating 3A at AC-15 for direct control of small loads
• Switching behaviour monostable for defined reset operation
• Contact material AgSnO2 for enhanced switching durability
• Fast buffering time minimum 20ms to bridge brief power interruptions
• Relay contact rating 3A at AC-15 for direct control of small loads
• Switching behaviour monostable for defined reset operation
• Contact material AgSnO2 for enhanced switching durability
**Applications**
• Suitable for protection of motor control circuits against phase loss
• Ideal for supervision of distribution panels in industrial automation
• Used with contactors to prevent operation under phase asymmetry
• Can be used for undervoltage interlock in production machinery
• Used for monitoring three-phase supplies in factory power systems

What supply voltage range does it accept for control supply?
It accepts AC control supply from 200V to 690V at 50–60 Hz with an operating range factor from 0.85 to 1.1 of the rated value.
How precise is the voltage measurement under temperature variation?
The device exhibits a relative temperature-related measurement deviation of 0.003%/°C and a relative metering precision of 5%.
What mechanical and electrical endurance can be expected from the switching element?
Mechanical life is typically 10 million cycles while electrical endurance at AC-15/230 V is around 100,000 operations.
How are wiring and connections implemented for installation?
Connections are screw terminals accepting solid or ferruled conductors from 0.5 mm² to 4 mm² with a recommended tightening torque of 0.6–0.8 N·m.
What environmental operating limits apply to the unit?
It is rated for operation between −25°C to +60°C, a maximum installation altitude of 2000m and up to 70% relative humidity.
