ABB 1SVR740830R0400 CM-ESS.2P Monitoring Relay is engineered for precise voltage monitoring in single-phase AC and DC electrical systems. Designed with DPDT contact configuration and compact dimensions of 85.6 mm height, 103.7 mm length, and 22.5 mm width, this relay easily mounts onto DIN rails, making it ideal for industrial, manufacturing, automation, and electrical panel applications.
This voltage monitoring relay offers four selectable measuring voltage ranges spanning from 3 to 600 VRMS. It provides configurable overvoltage and undervoltage monitoring with an adjustable hysteresis between 3-30%. The device operates on an open-circuit principle, energizing the output relay(s) when voltage thresholds are exceeded or fall below preset limits, with tripping delay adjustable from 0 to 30 seconds for the CM-ESS.2P variant.
Operating efficiently at supply voltages of 240 V AC and 240 V DC, the relay features two changeover contacts for flexible switching control. The push-in terminal type allows for secure and easy wiring. Its robust IP20 rating offers protection suitable for standard indoor environments. The relay is rated to function reliably within a temperature range up to 60°C and meets RoHS compliance requirements.
This product is manufactured in Germany, ensuring high-quality standards and reliability. It is tailored for use in electrical monitoring, industrial automation, control panels, and other applications requiring dependable voltage supervision across AC/DC circuits.
Supports single-phase voltage monitoring for AC and DC systems. User-configurable measuring ranges for versatile application. DPDT contacts facilitate multiple control functions. Compact DIN rail design integrates easily into existing installations.
Multiple LED indicators provide clear operational status.
