Product Positioning

The 3RT1456-6AB30-WH is a member of the Siemens SIRIUS 3RT.4 series S6 frame large power contactor family. It shares the same 3-pole architecture and 2NO+2NC auxiliary contact design as the 275A/690V AC-1 model in the same series, making it suitable for high-current motor control applications in industrial settings. Due to the limited availability of this specific version number in publicly available information, Kenxin Motors recommends that customers provide the equipment nameplate information before placing an order to confirm the coil voltage and version details, ensuring that the supplied specifications are fully compliant.

Core Product Advantages and Features

S6 Large Frame Series

With the same frame as the 3RT1456 series, the AC-1 rated current is up to 275A (690V/40°C).

3-pole main circuit design

Three sets of main contacts, suitable for switching applications between high-current three-phase motors and power distribution circuits.

2NO+2NC auxiliary contacts

Standard configuration includes 2 sets of normally open and 2 sets of normally closed auxiliary contacts, facilitating interlocking design of the control circuit.

Busbar type main circuit terminal

The main circuit adopts a connector design, which is suitable for high-current wiring and provides stable and reliable contact.
