Siemens 3RV1021-1CA10

Manufactured by a premium manufacturer that has dominated the automation industry for years, this Siemens motor starter protector is part of a world-class line of Siemens modules made to deliver quality and satisfaction. What should you look for when looking for the right motor starter? A quality motor starter will meet worldwide requirements as does the Siemens module 3RV1021-1CA10 which is manufactured meeting the application requirements of the industry.

The motor starter protector features a manual ON/OFF switch to ensure it is in the proper mode. It comes standard with an overload relay. It is a Class 10 relay. To ensure protection from any possible short circuit in your system, this module comes with a magnetic trip component.

Frame size is an excellent way to be informed that you are choosing the correct motor starter protector. The frame size for this module is a width of 45 mm. Current is another consideration when choosing the right motor starter protector. It must match your use of motors in your automation line. This unit has a current rate that is not rated to exceed the maximum which is25 Amps. This motor starter protector is made for motor modules that are using up to 20 hp at 600V.

Siemens delivers Class 10 protection from over currents by making use of a bimetallic heater element. The overcurrent protection extends to both AC motors and DC motors. How does this work exactly? The heaters use their bimetallic capabilities to directly sense the motor current. This renders the current insensitive to several problems that may happen as a result of common current fluctuations. It loses sensitivity to high frequencies and harmonic waves as well as sinusoidal currents and voltages.

Ambient temperature has also been considered and the issue of negative reactions has been dealt with by the use of a fourth strip. This fourth strip is also made to be bimetallic and its job is to be responsible for ambient temperature. As a matter of fact, it only reacts to the control panel’s ambient temperature. It then compensates for the change in temperature by preventing the unit from tripping if it detects that the temperature in the panel is higher than the motor’s ambient temperature. That is the kind of protection that keeps your automation line up and running and keeps you from overheating your motor.

Another safety precaution taken is the use of a feature on the module that is built into the unit. It is a differential trip bar. The differential trip bar will cause the motor starter protector to trip faster when necessary, like in the instance of a phase loss condition. This will bring down any possible damages to your motor if there is an accidental phase loss.

Another precaution taken for this motor starter unit is the magnetic trip elements. The magnetic trip elements are in each of the motor starter protectors and what it does to help you is to take the device offline in the case of a current crisis. Any time there is a current that is 12 times the maximum FLA dial setting it immediately goes offline to protect you and your automation line from distress.
