Product Positioning

The 3RT1054-1AP36 is one of the main models in Siemens' SIRIUS 3RT10 large contactor series. It features an S6 frame, providing a main circuit capacity of 115A, 55kW/400V, and comes standard with 2NO+2NC auxiliary contacts. The operating mechanism uses a 220-240V AC/DC universal coil, perfectly compatible with the single-phase control power supply commonly used in Taiwanese factories. It can be directly wired without the need for an additional transformer, making it a very common choice for large motor start-stop control panels.

Core Product Advantages and Features

220-240V AC/DC coil

The operating mechanism can be directly driven by 220-240V AC or DC power supply, compatible with common control power supplies in Taiwan.

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) facilitate interlocking circuits and status feedback.

Dual-terminal type

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

Wide range of applications

Commonly found in the power control panels of large water pumps, air compressors, fans, and process main units.
