The corresponding 3RT1076-6AF36 configuration is rated for AC-3/AC-3e applications up to 500 A and 250 kW at 400 V.
This makes it suitable for demanding three-phase motor applications.
Potential applications include:
The product is specified with mirror contacts, which are useful where auxiliary-contact information is needed for monitoring the state of the main contacts.
Mirror contacts can support applications such as:
The complete safety function must be designed according to the applicable machine-safety architecture.
The 3RT1076-6AF36 configuration uses screw terminals for the control and auxiliary circuits, while the main circuit uses busbar connections. Siemens documentation confirms this connection arrangement for the relevant SIRIUS 3RT family.
Screw terminals provide a familiar connection method for industrial panel builders and maintenance teams.
The product is specified with a conventional AC/DC coil arrangement. The corresponding Siemens configuration uses a specified AC/DC control supply, which should always be matched with the exact contactor marking and installation requirements.
This makes the contactor suitable for compatible industrial control circuits used with PLCs, relays and other control devices.
The corresponding 3RT1076-6AF36 configuration includes 2 NO + 2 NC auxiliary contacts.
These contacts can be used for:
This provides useful flexibility when integrating the contactor into automated motor-control systems.
The 3RT1076-6AF368K can be integrated into complete motor-control systems together with:
A typical arrangement is:
PLC / Control Circuit → Contactor Coil → Main Contacts → Motor
The auxiliary contacts can provide feedback to the control system for monitoring and interlocking.
