Frequently Asked Questions

What is the SIEMENS 3RV20110KA10 manual motor starter used for?

The SIEMENS 3RV20110KA10 is a non-reversing manual motor starter with integrated thermal overloads, designed to protect motors and electrical circuits from overloads and short circuits. It is commonly used in industrial automation, conveyor systems, and pump controls where reliable motor protection and manual switching are required.

What are the specifications of the SIEMENS 3RV20110KA10 manual motor starter?

The SIEMENS 3RV20110KA10 is a 3-pole, non-reversing manual motor starter rated at 1.25 A with a maximum voltage of 690V AC. It has a frame size (width) of S00 and includes integrated thermal units, so no separate thermal overload relay is needed. Operation is via a selector switch.

Where to buy the SIEMENS 3RV20110KA10 manual motor starter worldwide?

You can source the SIEMENS 3RV20110KA10 manual motor starter through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead times.

How to select the correct SIEMENS manual motor starter for a motor?

To select the correct SIEMENS manual motor starter, match the starter's rated current (e.g., 1.25 A for the 3RV20110KA10) to the motor's full-load current. Ensure the voltage rating (690V AC) and pole count (3) meet your system requirements. The integrated thermal units eliminate the need for separate overload relays.
