Frequently Asked Questions

What is the SIEMENS 3RT20251AC20 IEC magnetic contactor used for?

The SIEMENS 3RT20251AC20 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 manufacturing, HVAC, and material handling systems where reliable 24V AC coil control and 17 A rated current are required.

What are the specifications of the SIEMENS 3RT20251AC20 contactor?

The SIEMENS 3RT20251AC20 is a 3-pole, non-reversing IEC contactor rated 17 A with 3NO contacts and a 24V AC coil. It does not include integrated surge suppression. This model is designed for switching loads up to 17 A in industrial motor control and automation applications.

Where to buy the SIEMENS 3RT20251AC20 contactor worldwide?

3G Electric supplies the SIEMENS 3RT20251AC20 contactor to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial solutions provider, we source genuine Siemens parts and support procurement across 14 departments including electrical and controls.

How to select the right SIEMENS contactor for a 24V AC control circuit?

To select the right SIEMENS contactor, match the coil voltage (24V AC) and contact rating (17 A) to your load. Verify pole count (3) and contact configuration (3NO). For inductive loads like motors, ensure the contactor's rated operational current exceeds the full-load current. Consult Siemens technical data for application-specific derating.
