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.

What is the purpose of the ABB Monitoring Relay?
The ABB Monitoring Relay is designed to monitor three-phase mains for phase sequence and phase failure, ensuring that the phases are present and correctly ordered, which is crucial for the safe and efficient operation of three-phase electrical systems.
How is the ABB Monitoring Relay powered?
The relay is powered by the measuring circuit it is monitoring, which means it does not require a separate power supply.
What type of output contacts does the ABB Monitoring Relay have?
The relay features a single changeover (SPDT) contact, which allows it to switch between two circuits upon detection of a phase sequence or phase failure.
Can the ABB Monitoring Relay be mounted on a DIN rail?
Yes, the relay is designed for DIN rail mounting, which is a standard type of rail used for mounting circuit breakers and industrial control equipment inside equipment racks.
What is the width of the ABB Monitoring Relay?
The relay has a compact width of 22.5 mm, making it suitable for installation in space-constrained environments.
What are the voltage measuring ranges for the ABB Monitoring Relay?
The relay can measure three-phase mains with voltages ranging from 208 to 440 V AC.
What is the response time of the ABB Monitoring Relay?
The relay has a fixed response time of 500 ms for both start-up delay and tripping delay.
How can I tell if the ABB Monitoring Relay is operational?
The relay has a yellow LED indicator that illuminates to show the operational status and relay activation.
What is the rated operational current for the ABB Monitoring Relay?
The relay has a rated operational current of 4 A for resistive loads at 230 V AC in accordance with AC-12 utilisation category.
What environmental conditions can the ABB Monitoring Relay withstand?
The relay is designed to operate within an ambient temperature range of -20 to +60 °C and can handle damp heat, vibration, and shock within specified limits.
