1SVR730831R0400 ABB - CM-ESS.2S

The CM-ESS.2S is a voltage monitoring relay from ABB designed to ensure the reliable operation of electrical systems by continuously monitoring voltage levels. This relay provides comprehensive protection against over- and under-voltage conditions, safeguarding sensitive equipment from potential damage. It features two changeover (2c/o) contacts, offering versatile control and signaling capabilities for integration into various automation and control systems. The CM-ESS.2S monitors AC RMS voltage within a range of 3 to 600V, providing a wide application scope. It is powered by a 110-130VAC supply voltage. The relay trips when the voltage exceeds or falls below user-defined thresholds, activating the changeover contacts to initiate corrective actions or alarms. Its compact design facilitates easy installation in control panels and enclosures. The CM-ESS.2S is suitable for applications such as motor protection, generator monitoring, and power distribution systems. This voltage monitoring relay enhances system reliability and prevents costly downtime due to voltage-related issues. It also has adjustable hysteresis and time delay settings to prevent nuisance tripping and optimize performance for specific application requirements.
