ABB Multifunctional 180-280 VAC Monitoring Relays With Interrupted Neutral Monitoring

ABB offers multifunctional monitoring relays specifically designed to monitor electrical parameters within the voltage range of 180-280 VAC (Volts AC) while also incorporating interrupted neutral monitoring capabilities. These relays provide advanced monitoring and protection functions for electrical systems, ensuring safety and reliability. Here's an overview of ABB's multifunctional 180-280 VAC monitoring relays with interrupted neutral monitoring:

Key Features:

1. Voltage Monitoring: ABB's monitoring relays continuously monitor voltage levels across the electrical system within the specified range of 180-280 VAC. They detect overvoltage and undervoltage conditions to protect connected equipment from potential damage.

2. Current Monitoring: These relays monitor current levels in each phase of the system, detecting abnormal current conditions such as overload or underload. This helps prevent damage to motors, pumps, compressors, and other equipment.

3. Phase Sequence Monitoring: The relays ensure correct phase sequence and phase rotation in three-phase electrical systems. Proper phase sequence is essential for the safe operation of motors and other equipment.

4. Neutral Monitoring: ABB's relays with interrupted neutral monitoring can detect interruptions or faults in the neutral connection. This feature enhances safety by identifying neutral-related issues that can cause imbalances and potential hazards in the electrical system.

5. Adjustable Thresholds: The relays come with adjustable voltage and current thresholds, allowing users to set specific limits based on application requirements.

6. Fault Detection: ABB's monitoring relays can detect various faults such as phase loss, phase asymmetry, and phase reversal. They provide early warning of electrical issues to prevent equipment damage and downtime.

7. LED Indicators: Most models feature LED indicator lights for clear status indication, showing the relay's operating status and the presence of any faults or abnormalities.

8. Compact Design: ABB's monitoring relays are designed to be compact and suitable for installation in control panels, switchgear, motor control centers, or other electrical enclosures.
