Specification & Description
The ABB Monitoring Relay, part number 1SVR550824R9100, is a sophisticated device engineered to safeguard three-phase electrical systems from phase sequence and phase failure. This relay is an essential component for a wide array of industrial applications where the consistency of the power supply is crucial.
Designed to be powered directly by the measuring circuit, this monitoring relay is both efficient and reliable. It features a compact form factor with a width of just 22.5 mm, making it an ideal choice for installations where space is at a premium. The relay is equipped with a single changeover (SPDT) contact, allowing for straightforward integration into existing electrical setups.
The relay operates on a closed-circuit principle, ensuring that it de-energizes in the event of a phase sequence error or phase failure, after a fixed tripping delay. This functionality is critical for preventing potential damage to machinery and equipment that can occur due to incorrect phase sequences or the absence of a phase.
With a rated control supply voltage of 24 V dc and a quick response time of 500 ms, the ABB Monitoring Relay responds promptly to electrical issues, minimizing the risk of prolonged exposure to harmful conditions. The device can handle rated operational currents up to 4 A and is designed for easy mounting on a DIN rail, providing a secure and stable installation.
The relay's user interface includes an LED indicator that provides immediate visual feedback on the operational state, enhancing ease of monitoring and maintenance. The screw terminal connections ensure a robust and reliable electrical connection, suitable for a variety of industrial environments.
Overall, the ABB Monitoring Relay is a vital component for maintaining the integrity of three-phase systems, offering both protection and peace of mind for operators and maintenance personnel. Its robust design and reliable performance make it a preferred choice for industrial applications where electrical supply consistency is non-negotiable.
