Siemens 3RT1054-6AR36 Power Contactor 115A, 55kW, AC/DC 440-480V, 3-Pole, 2NO+2NC, Busbar, Screw Terminal Connection Original Brand New

Overview

The Siemens 3RT1054-6AR36 is a high-performance power contactor designed for reliable and efficient switching of electrical loads in industrial applications. As a key component of the SIRIUS 3RT product line, this contactor offers robust construction and advanced features for optimal performance and safety. It is a 3-pole contactor with a rated operational current of 115 A for AC-3e/AC-3 applications, suitable for motors up to 55 kW at 400 V.

The wide-range AC/DC control voltage (Uc: 440-480 V) allows for flexible integration into various control systems. Its conventional drive mechanism ensures straightforward operation, while the combination of busbar for the main circuit and screw terminals for the control and auxiliary circuits provides versatile connection options.

Key Features & Benefit

• High Performance: Handles a rated operational current of 115 A and is suitable for motor applications up to 55 kW at 400 V, making it ideal for demanding industrial environments.
• Versatile Control: Features a wide-range AC/DC control voltage (440-480 V), reducing the need for multiple contactor variants and simplifying inventory management.
• Integrated Auxiliary Contacts: Equipped with 2 NO (Normally Open) and 2 NC (Normally Closed) auxiliary contacts, providing essential feedback and control signals for complex automation systems.
• Robust & Reliable: Built with high-quality materials to ensure long-term durability and reliable operation under heavy-duty conditions.
• Flexible Connection Options: The main circuit connects via busbars for a clean and efficient power distribution setup, while the control and auxiliary circuits use conventional screw terminals for secure and accessible wiring.
• Compact Design: Despite its high power rating, the contactor maintains a compact form factor, saving valuable space within control cabinets.

Function

• Motor Switching: Efficiently and safely switches electric motors on and off.
• Load Control: Controls the flow of power to various electrical loads, including heaters, transformers, and lighting systems.
• Safety Interlocking: The integrated auxiliary contacts can be used for interlocking circuits, preventing simultaneous operation of conflicting equipment.
• Automation Integration: Serves as a critical interface between a control system (like a PLC) and the high-power load, enabling automated control of industrial processes.
