ABB 1SVR740830R0300

The CM-ESS.1P functions as a voltage monitoring relay within the CM series, specifically tailored for single-phase monitoring. It operates with a control supply voltage ranging from 24 to 240 V AC/DC and features a single changeover (SPDT) output contact capable of handling up to 250 V and 4 A.

This device employs a root mean square (RMS) measuring principle for both AC and DC voltages, supporting four distinct measuring ranges: from 3 to 30 V, 6 to 60 V, 30 to 300 V, and 60 to 600 V. Its configuration allows for monitoring either overvoltage or undervoltage conditions, with adjustable hysteresis set between 3% and 30% of the specified threshold.

Constructed to ensure durability, the CM-ESS.1P is equipped with maintenance-free Easy Connect Technology, featuring push-in terminals for simplified installation. The device measures 22.5 mm in width, 85.6 mm in height, and 103.7 mm in depth, weighing 0.126 kg. Additionally, it includes a transparent cover to prevent unauthorized adjustments. The product complies with various standards, ensuring reliable operation in industrial environments.
