Frequently Asked Questions

What is the SIEMENS 3RT20261AK643MA0 safety contactor used for?

The SIEMENS 3RT20261AK643MA0 is a SIRIUS 3RT safety contactor used to control and isolate power in industrial machinery and safety circuits. It is commonly applied in emergency-stop systems, safety gates, and conveyor controls where reliable disconnection is required to protect personnel and equipment.

What are the specifications of the SIEMENS 3RT20261AK643MA0 contactor?

This SIEMENS IEC magnetic contactor has 3 poles, a 25 A rating, and operates on 120V AC coil voltage. It is part of the SIRIUS 3RT safety contactor series and does not include integrated surge suppression. The manufacturer part number is 3RT20261AK643MA0.

Where to buy the SIEMENS 3RT20261AK643MA0 worldwide?
