Siemens 3RT1054-1AT36 SIRIUS Power Contactor 115A, 55kW, 575-600V AC/DC Original Brand New

Overview: Siemens 3RT1054-1AT36 SIRIUS Power Contactor

The Siemens 3RT1054-1AT36 is a robust, 3-pole power contactor from the globally recognized SIRIUS 3RT series, specifically engineered for switching motors and other loads up to 115A (AC-3e/AC-3) and 55 kW at 400 V.

This highly reliable component is a cornerstone of modern industrial control systems, offering high operational reliability and a compact design (Size S6). It is built for demanding automation and control tasks and is certified for worldwide use. The contactor features a conventional drive and versatile coil operation with a wide control voltage range of 575-600V AC (50/60 Hz) / DC.

Benefit

• High Performance: Safely and reliably switch high-current loads and motors up to 115A/55kW.
• Space Saving: Compact SIRIUS 3RT design allows for high packing density in control cabinets.
• Versatile Control: The wide 575-600V AC/DC operating coil simplifies inventory and is suitable for various global power systems.
• Integrated Auxiliary Contacts: The built-in 2 NO + 2 NC contacts reduce component count and wiring complexity for monitoring and interlocking circuits.
• Durable & Reliable: Designed for a long mechanical and electrical service life in harsh industrial environments.

Function & Application

The 3RT1054-1AT36 is primarily used as a main switching element for controlling three-phase asynchronous motors in applications such as:

• Pump Systems
• Ventilation and Air Conditioning
• Conveyors and Material Handling
• Machine Tools and Process Automation

It ensures efficient and reliable start/stop control and can be easily integrated into complex load feeders with other SIRIUS modular components (e.g., overload relays).
