Application / Monitoring function The thermistor motor protection relay CM-MSS monitors the winding temperature and thus protects the motor from overheating, overload and insufficient cooling in
Even for direct monitoring of explosion-proof motors in protection type Ex e and Ex d in hazardous areas (zones 1 and 2) and in the presence of combustible dust (zones 21 and 22).
The MSF 220 V is particularly suitable for the temperature monitoring at dry transformers. 3 PTC-circuits with different nominal response temperatures
Thermal overload relays. Thermal overload relays are economic electromechanical protection devices for the main circuit. They offer reliable protection for motors in
On the front of the relay, it provides a thermal adjustement dial, buttons for test, stop & reset, a trip indicator, trip auxiliary contacts 1NO+1NC.
Learn everything about thermal overload relays - how they work, types (bimetallic, electronic), applications, and why they''re essential for motor
This 0.1 to 6 amp thermal overload relay for 220 volt 3 phase circuits that I bought is really impressive. It has performed well in my industrial applications, playing a
