Checking for live stock

The ABB 1SVR730830R0400 CM-ESS.2S is a single-phase voltage-monitoring relay used to protect equipment from voltage issues. It continuously checks the supply voltage and reacts when levels go too high or too low. This helps prevent damage caused by unstable power conditions in control panels and electrical systems. It is typically installed in industrial and commercial settings where voltage reliability is critical, and an automatic response is required.

Key Performance Benefits of Buying the ABB DPDT Contacts Voltage Monitoring Relay

The CM-ESS.2S monitors overvoltage and undervoltage conditions on a single-phase supply. When the voltage exceeds the set limits, the relay switches its output contacts to trigger alarms, shut down equipment, or initiate corrective actions.

Detects overvoltage and undervoltage.
Works on single-phase systems.
Provides DPDT output contacts for control circuits.
Fits easily into protection and automation schemes.

Simple Setup and Reliable Switching

The relay uses DPDT (double-pole, double-throw) contacts, providing flexibility when connecting control or signalling circuits. Adjustable threshold settings allow users to define acceptable voltage limits based on the application.

Application Versatility of the Product

This voltage monitoring relay is typically used in:

Control panels
Motors and pumps
Power supply monitoring
Industrial automation systems
Equipment protection circuits
