Siemens 3UG5514-2BR20 3UG55142BR20 Network monitor No. of relay outputs: 2

Analogue adjustable monitoring relay Phase failure, phase sequence, asymmetry and undervoltage monitoring 3x 160-690 V AC, 15-70 Hz 2 changeover spring connection Analogue adjustable network monitoring relay SIRIUS 3UG5 for the monitoring of phase sequence,-failure and asymmetry and low voltage, e. g. in portable plants like air conditioning compressors, cooling containers, construction site compressors, cranes or solar and wind turbines.Worldwide use through international certificates. Small width means less space in a control cabinet. All versions with removable connection terminals. In addition to screw connection technology, the devices are also available throughout with spring connection for fast, maintenance-free and vibration-proof connection. Variants with a wide voltage range without auxiliary voltage can be used in all networks around the world.The comprehensive accessories, such as device identification labels, spare terminals and sealing covers, are uniform for all relays.The 3UG5 line monitoring relays replace the tried and tested 3UG4 series.SIRIUS relays - a program for all situations.
