ABB Monitoring Relay, SPDT Contact, DIN Rail Mount, 24 V DC/AC, 240 V AC, CM-MSS Series 1SVR730700R0100 CM-MSS.12S

ABB 1SVR730700R0100 CM-MSS.12S Monitoring Relay is a professional-grade temperature monitoring device designed for industrial control and automation applications. It features a single-pole double-throw (SPDT) contact configuration and mounts conveniently on a standard DIN rail, facilitating quick installation and integration into existing electrical panels. This relay supports dual supply voltages of 24 V DC/AC and 240 V AC, enabling flexible deployment across various power environments.

The device is engineered to monitor temperature effectively within a wide operational range of -25°C to +60°C, making it suitable for use in harsh industrial and commercial environments. The robust silver-nickel alloy contacts provide high conductivity and outstanding corrosion resistance, assuring consistent performance under demanding conditions. Screw terminals with IP20 and IP50 protection ratings safeguard wiring connections against accidental contact and ingress of solid objects larger than 12mm.

This ABB monitoring relay incorporates an automatic reset function, eliminating the need for manual intervention after tripping, thereby enhancing operational efficiency. The fast reaction time, under 100 milliseconds, provides rapid detection and response to elevated temperature conditions, preventing potential machinery damage due to overheating or overloading.

Visual status display is provided through green and red LED indicators, simplifying operational monitoring and troubleshooting. Compact dimensions, measuring 103.7 mm in length and 85.6 mm in height, ensure space-saving installation within control cabinets.

Ideal applications for this relay include industrial electronic devices, lighting control systems, and HVAC (Heating, Ventilation, and Air Conditioning) installations, where precise temperature monitoring and protection are paramount.
