Product Positioning

The 3RT1054-1NF36 is the electronic operating mechanism version of the Siemens SIRIUS 3RT10 large contactor family. It inherits the S6 base 115A, 55kW/400V main circuit rating and the 2NO+2NC auxiliary contact configuration. Unlike traditional electromagnetic coils, it is directly driven by a 24V DC signal through the PLC interface, resulting in more consistent operating timing and easier integration into automation control logic. It is suitable for large motors or power circuits with high requirements for opening/closing timing and signal integration.

Core Product Advantages and Features

Electronic operating mechanism

The coil is directly driven by a 24V DC signal through the PLC interface, replacing the traditional electromagnetic coil design.

S6 large chassis main circuit

The AC-3 has a rated current of 115A and a power output of up to 55kW at 400V, capable of handling large three-phase power loads.

Standard auxiliary contacts

Built-in 4 sets of instantaneous auxiliary contacts (2NO+2NC) to meet interlocking and signal feedback requirements.

Dual-terminal type

The main circuit uses box terminals, while the control and auxiliary circuits use screw terminals, offering high wiring flexibility.

High mechanical life design

According to third-party data, the mechanical life of the same series of electronic mechanism products reaches 10 million operations.

Made in Germany

Continuing the consistent manufacturing quality and international certification foundation of the SIRIUS 3RT10 series

3RT1054-1NP30

The 3RT1054-1NP30 shares the same main circuit specifications as the S6 frame electronic contactor in the same series. The AC-3 rated current is 115A, the power is 55kW at 400V, the control voltage is 200-277V AC/DC, and a 24V DC PLC interface is optional. It is recommended to confirm the part number with Kenxin Motor before placing an order.

3RT1054-1LA06

The 3RT1054-1LA06 is a Siemens SIRIUS 3RT10 series S6 base contactor, rated at 115A AC-3 and 55kW at 400V. It has 2NO+2NC auxiliary contacts and does not include an operating mechanism at the factory. An operating mechanism module can be added separately according to the field voltage to flexibly meet the needs of multi-voltage projects and spare parts.

3RT1054-1LA00

Similar to LA06, 3RT1054-1LA00 is a Siemens SIRIUS 3RT10 S6 base unit, rated at 115A AC-3, 55kW at 400V, with built-in 2NO+2NC auxiliary contacts and no operating mechanism. No explanation of the difference in the suffixes between LA00 and LA06 is available in publicly available information; it is recommended to consult and confirm the specifications before placing an order.
