Press Release Summary:
Sirius 3UG4 monitoring Relay can be flexibly adapted using wide range of parameter settings such as: phase sequence, asymmetry, undervoltage or overvoltage, delay times, and reset response. Unit has wide voltage range of 160-690 V. Unit is equipped with a display. Indication of actual value and type of fault facilitates installation and fault diagnostics. Together with contactor reversing combination, relay automatically corrects an incorrect phase sequence.
Original Press Release:
Monitoring Relays for Flexible Use
The new 3UG4 monitoring relays belonging to the Sirius family from Siemens Automation and Drives (A&D) can be flexibly adapted to the respective application. To achieve this, a wide range of parameter settings are available, such as phase sequence, asymmetry, undervoltage or overvoltage, delay times and reset response. The new units are characterized by a wide voltage range. All mains voltages worldwide are covered by the possible range of 160 to 690 V. The units are equipped with a display. Indication of the actual value and the type of fault facilitates installation and fault diagnostics. Together with a contactor reversing combination, the new monitoring relays automatically correct an incorrect phase sequence.
Background information:
Monitoring relays protect motors and plants by checking the setpoints of mains-related, load-dependent and application-based variables. This provides a high availability for stationary equipment for transportation of persons, such as elevators, and for transportable equipment such as refrigerated containers, cranes or site compressors.
