ABB CM-MPS Series Monitoring Relay, DPDT Contact Configuration, 180 to 280V AC Voltage Sensing Range - 1SVR730885R3300 CM-MPS.21S


This monitoring relay is a multifunctional device from the CM-MPS series, designed for effective monitoring in three-phase applications. With dimensions of 103.7 x 22.5 x 85.6mm, it operates within a voltage sensing range of 180-280 V AC and can handle electrical phases of up to three. The relay provides essential protection against voltage fluctuations and phase-related issues, ensuring system reliability.

Features & Benefits


• Monitors overvoltage and undervoltage conditions

• Detects phase imbalance and phase failure

• Adjustable tripping delay between 0 and 30 seconds

• Utilises DPDT contact configuration for versatile applications

• Suitable for mounting on standard DIN rails

• Wide operating temperature range from -25 to +60°C

Applications


• Used in industrial automation systems

• Suitable for three-phase electrical supply monitoring

• Employed in settings requiring phase sequence verification

• Ideal for needing neutral interruption detection

How does the adjustable tripping delay enhance reliability in operations?


The adjustable tripping delay allows custom configuration between instantaneous and 30 seconds, enabling users to optimise the response time to faults without unnecessary interruptions. This ensures a fine balance between prompt action and avoiding nuisance tripping during transient conditions.

What are the key advantages of utilising a DPDT configuration?


The DPDT configuration offers flexibility by allowing two separate circuits to be managed simultaneously, providing enhanced control over monitoring and switching operations in various applications. This is particularly beneficial in complex systems where multiple conditions need to be monitored at once.

In which scenarios should the voltage sensitivity features be applied?


These voltage sensitivity features are crucial in environments prone to fluctuations, ensuring that equipment operates only within safe voltage limits. By monitoring both over and undervoltage events, it protects machinery from damage and enhances operational safety.
