Siemens SIRIUS 3RT1054-1LA00 contactor body without operating mechanism

Product Positioning

Both 3RT1054-1LA00 and 3RT1054-1LA06 are "bare" versions of the Siemens SIRIUS 3RT10 large contactor, with identical main contact specifications of 115A, 55kW/400V and 2NO+2NC auxiliary contacts. Neither is shipped without an operating mechanism. Currently, publicly available information does not clearly indicate the specific differences between the LA00 and LA06 suffixes, which may involve packaging, batch, or internal configuration codes. It is recommended to confirm that the model number perfectly matches your requirements before purchasing.

Core Product Advantages and Features

Excluding operating mechanism

The device is shipped without a coil/operating mechanism. A corresponding voltage mechanism module must be selected and matched separately before it can be powered on and used.

S6 large chassis main circuit

The AC-3 model has a rated current of 115A and a power output of up to 55kW at 400V, making it suitable for large-scale three-phase power control applications.

Standard auxiliary contacts

Built-in 4 sets of instantaneous auxiliary contacts (2NO+2NC), which can be directly used for interlocking and status feedback.

Differences in the last two digits need to be confirmed.

Compared to LA06, publicly available information does not clearly specify the actual differences of LA00; it is recommended to confirm these differences before purchasing.

Dual-terminal type

The main circuit uses square terminals, while the control and auxiliary circuits use screw terminals, making wiring and installation convenient.
