Frequently Asked Questions

What is the function of the CM-MSS.31 motor protection relay?

The CM-MSS.31 motor protection relay is designed to monitor the winding temperature of motors, offering protection against overheating, overload, and insufficient cooling. It utilises PTC resistor sensors to measure the motor's temperature and triggers a response if abnormal temperatures are detected.

Can the CM-MSS.31 relay detect both wire short-circuits and interruptions?

Yes, the CM-MSS.31 relay features dynamic interrupted wire detection and short-circuit monitoring of the sensor circuit, which allows it to detect and respond to both conditions effectively.

How can I reset the CM-MSS.31 after a fault has occurred?

The CM-MSS.31 can be reset manually using the front-face Test/Reset button, remotely via a connected push button between terminals S1 and T2, or automatically if S1 and T2 are jumpered, depending on the configuration.

What type of terminals does the CM-MSS.31 offer for electrical connections?

The CM-MSS.31 is available with two types of terminal connections: screw connection technology with double-chamber cage connection terminals and the Easy Connect Technology with push-in terminals.

Is the CM-MSS.31 suitable for use in explosive atmospheres?

The CM-MSS.31 is suitable for use with explosion-protected motors, with the sensor line being conducted into the explosive atmosphere while the relay itself must be installed outside the potentially explosive atmospheres.

What are the LED indicators on the CM-MSS.31 used for?

The CM-MSS.31 is equipped with LED indicators that provide status information about the control supply voltage, the output relay status, and fault messages, helping to diagnose issues quickly.

What is the rated control supply voltage range for the CM-MSS.31?
