Siemens 3TS3511-0XM0 3TS Converter duty contactor

Here is the parameter introduction of Siemens 3TS3511-0XM0:

Rated Current: It has a rated current of 40A, which means it can handle a continuous current of 40A under normal operating conditions. This rating is suitable for various industrial applications where the load current is within this range.

Control Coil Voltage: The control coil operates at 220V AC. This standard voltage allows for easy integration into most industrial power supply systems. It ensures reliable activation and de - activation of the contactor, 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 makes it applicable to a wide range of industrial applications involving higher voltages.

Auxiliary Contacts: It is equipped 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.

Product Class: It belongs to product class C, which means it is manufactured or produced to order and cannot be reused, re - utilized, or returned for credit.

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.

Installation Method: The installation method can be either rail - mounted or screwed - down, providing flexibility in different installation scenarios. Compared with other similar products, it has a higher operating frequency and control capacity.
