The thermistor motor protection relay CM-MSS.41
monitors the winding temperature of motors and
protects them from overheating, overload and
insufficient cooling.
The device is available with two different terminal
versions. You can choose between the proven
screw connection technology (double-chamber
cage connection terminals) and the completely
tool-free Easy Connect Technology (push-in
terminals).
