Siemens 3TS3500-0AF02-8K 3TS Converter duty contactor

Here is the parameter introduction of the Siemens 3TS3500-0AF02-8K:

Rated Current: The rated current of this contactor is 40A, which means it is capable of handling a continuous current of 40A under normal operating conditions. This rating makes it suitable for a variety of industrial applications where the load current is within this range.

Control Coil Voltage: The control coil of the 3TS3500-0AF02-8K operates at 220V AC. This is a standard voltage that allows for easy integration into most industrial power supply systems, ensuring reliable activation and de - activation of the contactor, and enabling precise control of the connected electrical circuit.

Rated Voltage: The rated insulation voltage is 690V. It is suitable for use in three - phase AC circuits with a maximum working voltage of 690V, which enables it to be applied in a wide range of industrial applications involving higher voltages.

Auxiliary Contacts: It comes with 1 normally open (NO) and 1 normally closed (NC) auxiliary contact. These auxiliary contacts are useful for various control and signaling purposes, such as providing feedback signals to indicate the contactor's status, enabling interlocking with other electrical components, or controlling additional related circuits.

Frequency: It is designed for AC 50Hz or 60Hz power supply systems, which is suitable for most common industrial power frequencies.

Contact Material: The main and auxiliary contact materials are composed of electrically conductive silver alloys, which have a long service life and good contact reliability. This ensures stable electrical contact and low contact resistance during operation, reducing the risk of arcing and contact burnout.

Arc-Quenching Chamber: The arc - quenching chamber is of a closed - type design and is made of flame - retardant materials to prevent the arc from splashing outward. For currents le≥32A, a metal arc - separating plate is installed to enhance the arc - quenching effect and ensure the safety of personnel and adjacent electrical equipment.

Overall Structure: The contactor adopts a direct - acting motion mechanism with double - break contacts, having three pairs of normally open main contacts. The contact support and the armature are elastically locked and connected, eliminating weak links. The action mechanism is flexible, and manual inspection is convenient. The compact structure design can prevent foreign matter and dust from entering the moving parts, and the wiring terminals are covered to prevent direct human contact with live parts.
