Siemens Monitoring Relay, 5A Maximum Current Sensed, 160/690V AC Supply Voltage - 3UG5511-1AR20
This monitoring relay monitors three-phase supply sequence and voltage within industrial control panels. It detects phase order and provides a single changeover contact for control logic, operating on AC supplies across a wide voltage band and tolerating typical industrial disturbance levels. The unit is intended for DIN-rail mounting where compact, rugged line supervision is required.
Features & Benefits
• Monitors 3-phase sequence and prevents incorrect rotation
• SPDT contact rated for practical switching up to 5A
• Wide AC sensing range 160–690 V for flexible supply conditions
• Galvanic isolation between input and outputs for safer circuits
• SPDT contact rated for practical switching up to 5A
• Wide AC sensing range 160–690 V for flexible supply conditions
• Galvanic isolation between input and outputs for safer circuits
**Applications**
• Suitable for protecting motor starters from phase reversal
• Ideal for integration into machine control panels
• Used with contactors in three-phase distribution systems
• Can be used for line supervision in manufacturing plants

What control supply frequencies are supported?
It accepts AC control supplies at both 50 Hz and 60 Hz within the specified operating range factors of 0.85 to 1.1.
How does it behave during short interruptions?
The device provides a minimum buffering time of 20ms to bridge brief supply disturbances before tripping.
What connection options are available for field wiring?
Screw terminals accept solid or finely stranded conductors from 0.5 mm2 up to 4 mm2 with a stripping length of 10 mm and 0.6–0.8 N·m tightening torque.
What environmental limits must be observed during installation?
It operates between -25 °C and +60 °C, with a maximum recommended installation altitude of 2000m and up to 70% relative humidity during use.
How is mechanical mounting achieved?
It mounts on a 35mm DIN rail and includes removable terminals for both main and auxiliary circuits for simplified wiring and maintenance.
