Siemens Monitoring Relay, 5% Relative Measurement Accuracy, 0.1 to 20s Time Delay - SIRIUS Series - 3UG4513-1BR20


Protect your industrial equipment against power supply issues with this voltage monitoring relay from Siemens. By tripping a circuit breaker when your system's voltage drops too low, it prevents damage caused by malfunctioning equipment. As the device has an adjustable input voltage range between 200 and 690V AC, it's widely compatible and you can adapt it to fit your circuit. It closely monitors your supply voltage with 5% relative accuracy and has a maximum response time of 450ms, which ensures your circuit breaker receives a signal quickly and before faults can become hazardous. You'd use a monitoring relay like this one to protect assembly lines and motor-driven appliances.

Features & Benefits


• Built-in time delay between 0.1 and 20s for applications with limited anticipated undervoltage
• Automatically resets after tripping for minimal system downtime
• Low power consumption of 2W for energy-efficient voltage monitoring
• Broad operating temperature range between -25°C and +60°C for use in tough industrial conditions

How do I set the input voltage and time delay on this monitoring relay?


You can adjust this relay's input voltage and time delay using a crosshead screwdriver on the front-facing dials.
