The contactor should always be selected according to the motor/load current, utilization category, operating voltage and application duty.
The corresponding Siemens configuration is rated for AC-3/AC-3e applications up to 400 A and 200 kW at 400 V.
This makes the contactor suitable for demanding three-phase motor applications such as:
The actual application must be matched to the required utilization category and motor characteristics.
The product description specifies mirror contacts. Mirror contacts can provide useful auxiliary information related to the state of the main contacts.
They can support:
For safety-related applications, the complete control and safety architecture must be designed according to the applicable requirements.
The corresponding Siemens configuration uses screw terminals for the control and auxiliary circuits, while the main power circuit uses busbar connections.
This provides a familiar and practical connection method for industrial panel builders and maintenance teams.
The 3RT1075-6AP368K is specified with a conventional AC/DC coil. The corresponding Siemens configuration uses a 220–240 V AC/DC control supply.
This makes it suitable for compatible industrial control circuits using the specified control voltage.
Always verify the coil voltage against the actual product marking before installation.
The corresponding configuration includes 2 NO + 2 NC auxiliary contacts.
These auxiliary contacts can be used for:
This allows the contactor to be integrated into automated motor-control systems.
The 3RT1075-6AP368K can be incorporated into complete motor-control systems alongside:
A typical arrangement can be:
Control System → Contactor Coil → Main Contacts → Motor
Auxiliary contacts can provide feedback and interlocking signals to the control system.
