Siemens 3RT1054-1SF36 Power Contactor, 115A, 55kW, AC/DC F-PLC Original Brand New

Overview

The Siemens 3RT1054-1SF36 is a robust, high-performance power contactor from the SIRIUS 3RT1 family, designed for reliable switching of electric motors and other loads in demanding industrial applications. This 3-pole contactor is rated for $115\text{ A}$ (AC-3e/AC-3) and a power rating of $55\text{ kW}$ at $400\text{ V}$.

A key feature of this model is its advanced electronic drive with a wide-range control voltage of $96\text{–}127\text{ V}$ AC/DC, making it highly versatile and resistant to voltage fluctuations. Furthermore, it includes a dedicated F-PLC input at $24\text{ V DC}$ for seamless integration into safety-related or complex automation systems.

Benefit and Advantages

• Robust & Reliable: Built as part of the trusted Siemens SIRIUS 3RT line, ensuring long mechanical and electrical service life for continuous operation.
• Flexible Control: Features a wide-range AC/DC electronic coil ($96\text{–}127\text{ V}$) for maximum flexibility and stable operation under varying supply conditions.
• Safety Integration: Dedicated F-PLC input ($24\text{ V DC}$) allows for direct connection to safety PLCs, simplifying wiring for safety-related circuits (e.g., emergency stops).
• High Power Handling: Rated at $115\text{ A}$ (AC-3e/AC-3) and $55\text{ kW}$, making it suitable for high-demand motor control applications (e.g., large pumps, fans, or compressors).
• Integrated Auxiliary Contacts: Comes standard with $2\text{ NO}$ and $2\text{ NC}$ auxiliary contacts, reducing the need for external accessories and simplifying control circuit design.

Function and Application

The Siemens 3RT1054-1SF36 power contactor is primarily used for switching and controlling three-phase asynchronous motors. Its applications span various industries, including:

• Motor control in machinery and production lines
• Switching large resistive or inductive loads (AC-1)
• Integration into complex control panels and motor control centers (MCCs)
• Use in systems requiring high reliability and PLC-based safety shutdown (F-PLC).
