3RT1064-6LA06

The 3RT1064-6LA06 is a bare body of the Siemens SIRIUS S10 large contactor. It does not include an operating coil at the factory; however, a voltage module can be selected separately according to site requirements. It is a three-pole 225A contactor, providing 110kW at 400V, and comes standard with 2NO+2NC auxiliary contacts. It is suitable for centralized spare parts management or applications requiring customized coil voltage.

Siemens SIRIUS 3RT1064-6LA06 Large Contactor without Operating Mechanism (Bare Body)

Product Positioning

The 3RT1064-6LA06 is a coilless version of the Siemens SIRIUS S10 large power contactor. It only provides the main switching mechanism at the factory, without the operating coil, allowing for convenient selection of corresponding modules based on the field control voltage. It is commonly used for standardized spare parts management. The main circuit specifications are consistent with standard models in the same series: three-pole, 225A AC-3 rated current. Kenxin Motors provides genuine original parts and selection suggestions.

Core Product Advantages and Features

coilless bare body

The operating mechanism coil is not included in the shipment. Modules can be flexibly selected according to the field control voltage to reduce the number of spare parts available.

S10 large contactor body

Three-pole design, AC-3 rated current 225A, power 110kW at 400V, main circuit specifications are consistent with the same series.

Standard auxiliary contacts

It has four sets of auxiliary contacts (2 NO + 2 NC) for easy interlocking control and feedback signal wiring.

Bus main circuit terminals

It can accept 70 to 240 mm² stranded wire, suitable for high current panel wiring and maintenance/replacement.

Long life mechanism

With a mechanical life of 10 million operating cycles, it is suitable for industrial applications requiring frequent start-stop cycles.

Original factory authorized supply

Kenxin Motors is an authorized distributor of Siemens and can assist in selecting and matching corresponding voltage coil modules.
