Product Description
ABB 1SVR730760R0400 CM-SFS.21S Monitoring Relay is a high-precision current monitoring device designed for single-phase AC and DC systems. This relay supports a current sensing range from 0.1mA to 100mA and operates on a supply voltage of 240 V DC or 240 V AC, making it highly versatile for industrial applications. It features a DPDT contact configuration with two changeover contacts that can be configured either together as a double pole changeover or independently for monitoring overcurrent and undercurrent conditions.
The relay is mounted on a DIN rail and comes with screw terminals for secure electrical connections. The monitoring device uses a measuring principle that allows simultaneous monitoring of over- and under-currents with configurable open or closed circuit operation and adjustable ON/OFF delay times. It includes a fixed hysteresis of 5% and supports both latching and non-latching functions, allowing operational customization.
The compact relay measures 103.7mm in length, 85.6mm in height, and only 22.5mm in width, making it suitable for space-constrained control panels. It is rated IP20 for protection and is designed to operate within a temperature range up to 60°C. The device includes three LED status indicators to facilitate easy monitoring of operating conditions in real-time.
Typical industrial applications include electrical automation, condition monitoring, manufacturing process control, and equipment protection where precise current threshold detection is critical. The product is manufactured in Germany, ensuring adherence to quality standards and RoHS compliance for environmentally safe operation.
Monitors undercurrent and overcurrent in single-phase AC/DC systems. Configurable switching and time delays enhance protection features. Compact DIN rail mount with screw terminals for easy installation. 3 LED indicators provide visual operational status.
