Siemens SIRIUS 3UG4 Monitoring relay 3UG4512-1BR20 Monitoring relay for mains and three-phase voltages
Product details
Description SIRIUS 3UG4 Monitoring Relay
The SIRIUS 3UG4 monitoring relays provide optimal protection for machines and systems. They are permanently installed to protect against over- or undervoltage or for complete network monitoring in portable systems. Monitoring the load of motors and the functionality of electrical consumers is also an application area for the 3UG4 monitoring relays, which offer current, power factor (cos phi), and active power monitoring. The 3UG4 monitoring relays also monitor non-electrical parameters such as fill levels or the speed of motors.
Special features: Usable in all networks worldwide due to wide voltage range, continuous display of actual value and error type in the digital variants, all versions with removable terminals, compact width.
