Siemens 3RT1054-3AS36 Power Contactor, 115A, 55kW, SIRIUS 3RT1 Original Brand New

Overview

The Siemens 3RT1054-3AS36 power contactor is a high-performance switching device from the trusted SIRIUS 3RT1 family, engineered for controlling three-phase motors and other demanding industrial loads. Rated for operation up to 115 A (AC-3e/AC-3) and capable of switching motors up to 55 kW at 400 V, this robust 3-pole contactor is ideal for various motor control applications, including standard switching and safe motor shutdown in demanding environments.

Benefit

1. High-Power Motor Control: Safely and reliably switch motors up to 55 kW, making it a powerful solution for heavy industrial machinery and equipment.
2. Flexible Control Voltage: The wide 500-550 V AC/DC control voltage range (Uc) provides excellent versatility and simplifies stock-keeping, ensuring reliable operation in diverse control systems.
3. Enhanced Reliability: Incorporating both spring-loaded terminals (for auxiliary circuits) and secure box terminals (for the main circuit) ensures maximum connection reliability and faster, more robust wiring.
4. Global Standard: As a genuine Siemens SIRIUS component, the 3RT1054-3AS36 guarantees compliance with international industrial standards and seamless integration into the SIRIUS modular system.

Function

This 3-pole power contactor acts as an electrically controlled switch, primarily used to turn electric motors ON and OFF. When the control voltage (500-550V AC/DC) is applied to the coil, the main contacts close, connecting the 115 A load to the power supply. The AC-3e/AC-3 rating confirms its suitability for standard squirrel-cage motor switching applications.
