Thermistor motor protection relays are control units for built-in thermal protection (PTC) for rotating electrical machines, to monitor the winding temperature of motors and generators using PTC sensors and to protect them from abnormal overheating.
The electrical motors’ winding temperatures are tracked and measured by the thermistor relay. The windings’ high temperature serves as a safeguard against overload, overheating, and insufficient cooling for motors.
The resistance of a thermistor, a particular type of resistor, changes quickly with even a slight change in temperature.
In other words, it is a resistor where a tiny change in temperature causes a rapid change in the flow of electric current. The words “thermal” and “resistor” are combined to form the word “thermistor.”
The Global Thermistor Monitoring Relay market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The thermistor motor protection relay CM-MSS.21 keeps track of the temperature of a motor’s windings and guards against overload, overheating, and inadequate cooling.
There are two different terminal versions for the device. Choosing between the entirely tool-free Easy Connect Technology (push-in terminals) and the tried-and-true screw connection technology (double-chamber cage connection terminals) is possible.
one measurement circuit, Automatic reset, sensor circuit short-circuit monitoring, dynamic wire interruption detection, and non-volatile fault storage are some of the features.
LEDs to differentiate between various failure modes.Protected supply and measurement inputs from overvoltage.
Increased interference immunity in accordance with EN 62061 with the “Fail-Safe” evaluation criterion, as of the most recent iteration of the product standard IEC 60947-8.
