Product Positioning

The 3RT1054-1AF36 is a member of the Siemens SIRIUS 3RT10 large contactor series. It features a 115A, 55kW/400V main circuit capacity in an S6 frame and comes standard with 2NO+2NC auxiliary contacts. The operating mechanism uses a 110-127V AC/DC universal coil, corresponding to control power levels common in US standards or some export equipment. It is suitable for export machines, international projects, or large power circuits in existing 110V control systems.

Core Product Advantages and Features

110-127V AC/DC coil

The operating mechanism can be directly driven by a 110-127V AC or DC power supply, corresponding to US and other export control power supplies.

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.

Suitable for export machines

Commonly used in export equipment or international project power control panels that require control voltage conforming to US standards.
