ABB CM-ESS.1S Voltage Monitoring Relay, 24-240V AC/DC, Multi-Range, DIN Rail Mount - 1SVR730830R0300

The ABB CM-ESS.1S Voltage Monitoring Relay is engineered to provide exceptional voltage monitoring for your electrical systems, accommodating a broad voltage range from 24-240V AC/DC. This relay is designed to protect your equipment from over or under voltage conditions, ensuring optimal performance and longevity. It features multi-range input capabilities and secure screw/cage terminals for reliable connections. Ideal for DIN rail mounting, it fits seamlessly into various control panels and distribution boards. Certified by UL, GL, GOST, CB, CCC, and RMRS, this relay meets international standards for reliability and performance. Compact in size, it measures 3.37 inches in height, 0.89 inches in width, and 4.08 inches in depth, with a weight of approximately 5.94 ounces. The CM-ESS.1S is perfect for applications that demand precise voltage monitoring to protect critical electrical components and systems. It operates with a rated control supply voltage of 24 - 240 V AC/DC and features a 1 c/o (SPDT) output contact rated at 250 V / 4 A. The relay offers RMS measuring for DC and AC voltages across four measuring ranges: 3-30 V, 3-60 A, 30-300 V, and 60-600 V, functioning on the open-circuit principle. Configurable for over- or undervoltage monitoring, it allows for adjustable hysteresis within 3 to 30% of the threshold value. An optional sealable transparent cover is available to prevent unauthorized adjustments, and the device utilizes screw connection technology with double-chamber cage connection terminals for enhanced security.
