Frequently Asked Questions

What is the SIEMENS 3RT20171BB41 contactor used for?

The SIEMENS 3RT20171BB41 is a non-reversing IEC magnetic contactor used to switch motors, lighting, and other inductive loads in industrial control panels. It is commonly applied in conveyors, pumps, and HVAC systems where reliable on/off control of three-phase circuits is required.

What are the specifications of the SIEMENS 3RT20171BB41 contactor?

This SIEMENS contactor has 3 poles and 3 normally open (3NO) contacts, rated at 12 A with a 24 VDC coil. It does not include integrated surge suppression. The manufacturer part number is 3RT20171BB41. It is designed for non-reversing applications in IEC motor control circuits.

Where to buy the SIEMENS 3RT20171BB41 contactor worldwide?

You can source the SIEMENS 3RT20171BB41 contactor 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 time; we supply genuine Siemens components for industrial applications.

How to select the right SIEMENS contactor for a 24V DC coil application?

For a 24 VDC coil application, ensure the contactor's coil voltage matches your control circuit. The SIEMENS 3RT20171BB41 is a 3-pole, 12 A, non-reversing contactor with a 24 VDC coil. Verify the load current and voltage rating, and consider adding external surge suppression if needed, as this model lacks integrated suppression.
