Specification & Description

The Siemens 3UG4512-1BR20 is a sophisticated analogue monitoring relay designed for meticulous network monitoring, particularly in the detection of phase failure and sequence issues. This relay operates with a voltage range of 160 to 690 V AC and is compatible with 50 to 60 Hz AC power systems, making it versatile for a broad spectrum of industrial applications.

Crafted with precision, the 3UG4512-1BR20 features two change-over contacts and employs screw terminal connections for secure and reliable wiring. Its compact dimensions, 22.5 x 91 x 92 mm, allow for efficient use of space within electrical cabinets.

The relay is equipped with an LED display that provides clear indication of operational status, enhancing ease of monitoring and diagnostics. It is also designed to withstand challenging industrial environments, with a robust construction that offers an insulation voltage resistance rated at 690 V for overvoltage category III and a degree of pollution 3, ensuring durability and long-term performance.

The 3UG4512-1BR20 is the successor to previous models 3UG3513-1BL50 or 3UG3513-1PB50, offering enhanced features and improved functionality. Its design is focused on ensuring consistent and reliable operation, with a protection class of IP20 and resistance to shock and surge voltages, making it a reliable choice for safeguarding critical electrical systems against phase-related anomalies.

This monitoring relay is an essential component for industrial settings where precise voltage monitoring is crucial, such as manufacturing plants, processing facilities, and other applications where electrical supply integrity is paramount.
