- Description
The ABB CM-SRS.11S (SKU: 1SVR730840R0200) is a single-phase current monitoring relay designed for precise over- and under-current detection in industrial automation and control panel applications. Part of the ABB CM single-phase monitors series, the CM-SRS.11S monitors AC/DC currents from 3 mA to 1 A RMS across a wide supply voltage range of 24–240 V AC/DC, providing one changeover (1C/O) output contact for reliable protection and signalling. Its compact 22.5 mm DIN rail housing makes it ideal for space-constrained control cabinets.

Frequently Asked Questions
What current range does the CM-SRS.11S monitor?
The CM-SRS.11S monitors currents from 3 mA to 1 A RMS, making it suitable for a wide range of low-current monitoring applications in industrial and commercial control systems.
What supply voltages are compatible with the CM-SRS.11S?
The relay accepts a universal supply voltage of 24–240 V AC/DC, eliminating the need for separate power supplies in most standard control panel applications.
What output does the CM-SRS.11S provide?
The CM-SRS.11S provides one changeover (1C/O) output contact, enabling both normally open (NO) and normally closed (NC) circuit configurations for alarm or control functions.
What DIN rail width does the CM-SRS.11S occupy?
The CM-SRS.11S fits a standard 22.5 mm DIN rail slot, consistent with IEC 60715 DIN rail mounting standards.
