ABB 1SVR730722R1400 CM-MSS.21S monitoring relay offers reliable temperature monitoring and protection for motors and industrial equipment. Featuring a single-pole double-throw (SPDT) contact configuration and DIN rail mounting, this device is specially engineered for monitoring motor winding temperatures using PTC type A sensors, ensuring accurate temperature tracking to prevent overheating and motor damage.
This relay supports supply voltages of 24 V dc, 24 V ac, and 240 V ac, making it suitable for diverse industrial power systems. Its compact design with dimensions of 103.7 mm length, 85.6 mm height, and 22.5 mm width facilitates easy installation in control panels. The device operates in environments from -25°C to 60°C and meets UL safety standards.
The automatic reset function allows the relay to reset once the monitored temperature falls below the threshold, minimizing downtime without manual intervention. Non-volatile fault storage captures fault events to aid diagnostics, while integrated overtemperature, overload, and short-circuit monitoring enhance motor protection. The relay's screw terminal type provides secure electrical connections.
Applications include temperature monitoring in motor winding protection, integration within industrial motor control systems, and usage in automation and mechanical environments. The relay's fast safety response time of under 100 milliseconds ensures prompt reaction to temperature anomalies.
Monitors motor winding temperature to prevent overheating. Versatile SPDT contact control configuration. DIN rail mounting for straightforward panel integration. Automatic reset after temperature normalization. Non-volatile fault memory for diagnostic purposes.
Protection against overtemperature, overload, and sensor faults. Complies with UL industry safety standards. Compact size suitable for tight panel spaces. Wide temperature operating range from -25°C to 60°C. Fast response time below 100 milliseconds for safety functions.
