Information About 3UG4615-1CR20
The Siemens 3UG4615-1CR20 is a compact and reliable phase monitoring relay designed to protect three-phase systems by monitoring phase sequence, phase failure, undervoltage, and overvoltage conditions. Part of the SIRIUS 3UG4 series, it supports a wide voltage range from 160 to 690 V AC and offers adjustable time delay and hysteresis settings. Designed for industrial automation and motor protection, this relay enhances system safety by detecting critical voltage disturbances before they can damage equipment.
Key Features:
- Phase Sequence and Failure Monitoring:
Ensures correct rotation direction and continuous operation by detecting incorrect phase sequence and phase loss in three-phase networks. - Wide Voltage Range – 160 to 690 V AC:
Suitable for global applications with broad compatibility across industrial power supply standards. - Undervoltage and Overvoltage Detection:
Monitors line voltage for deviations outside preset thresholds, providing early protection against voltage-related equipment failures. - Adjustable Hysteresis – 1 to 20 V:
Customizable hysteresis values help reduce nuisance tripping in environments with voltage fluctuations. - Time Delay Settings – 0 to 20 Seconds:
Allows configurable delay response for undervoltage and overvoltage conditions, helping avoid false alarms during transient dips or spikes. - Two Changeover (CO) Contacts:
Provides individual output contacts for both Umin and Umax conditions, enabling integration into alarm or control circuits. - Screw Terminal Connection:
Standard screw terminals ensure durable and secure wiring in control panels. - DIN Rail Mounting:
Designed for easy and fast installation on DIN rails, suitable for space-constrained electrical enclosures. - Industrial Standards Compliance:
Meets IEC specifications for voltage monitoring relays, supporting use in safety-critical industrial applications. - Phased-Out Product Notice:
This model has been officially phased out. The recommended successor is Siemens 3UG5616-1CR20, which offers digital monitoring, enhanced functionality, and greater configuration flexibility.
The 3UG4615-1CR20 has served as a dependable solution for voltage and phase fault detection in industrial power systems. With its successor, 3UG5616-1CR20, Siemens continues to provide modern and efficient protection technology for today's automation challenges.
