Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The Siemens 3UG4614-1BR20 is a digitally adjustable SIRIUS 3UG4 network monitoring relay. It performs phase sequence, phase failure, phase asymmetry and undervoltage monitoring for three-phase AC systems (160-690 V, 50/60 Hz). Installed via screw terminals, it outputs via two changeover (SPDT) contacts. Typically used for phase failure detection, sequence monitoring and undervoltage protection in motor control circuits and industrial power systems. 3UG4614-1BR20 is now in phase-out status, with 3UG5514-1BR20 as the preferred successor.
Best Suited For
- Phase failure protection in three-phase motors
- Phase sequence verification in control panels
- Undervoltage detection in power distribution
- Replacement in existing SIRIUS monitoring applications
