1 pcs : 3UG45131BR20 - Industrial Relays 3PH VOLTAGE MONITOR

SIRIUS 3UG4 Monitoring Relays Siemens SIRIUS 3UG4 Monitoring Relays monitor the most diverse electrical parameters in the feeder and provide reliable protection against damage in the plant. These Siemens relays feature freely parameterizable threshold values and manifold adjustment options, and the devices also offer conclusive diagnostics and can autonomously correct an incorrect phase sequence. Numerous versions include an IO-Link interface for connection to the controller. SIRIUS 3UG4 monitoring relays also monitor mechanical variables. The level monitoring relays ensure reliable 1- or 2-point controls and alarm messages in the event of overflow or dry running. The speed monitoring relays check whether the nominal speed of motors, shafts, or powered wheels is exceeded or not reached. These relays are suitable for all functions requiring continuous pulse signal monitoring.
