Siemens 3RT1054-2AP36 SIRIUS Power Contactor, 115A, 55kW, 220-240V AC/DC Coil, Size S6, Spring-Loaded Terminal Original Brand New

Overview

The Siemens 3RT1054-2AP36 SIRIUS power contactor is a high-performance, 3-pole switching device engineered for reliable motor control and switching applications up to 115 A (AC-3e/AC-3) and a rated operating power of 55 kW at 400 V. Part of the globally approved SIRIUS modular system, this robust Size S6 contactor is designed for flexibility and efficiency in industrial control panels. It features a conventional AC/DC wide-voltage operating mechanism (220-240 V Uc), a reliable 2 NO + 2 NC auxiliary contact configuration, and modern spring-loaded terminals for control and auxiliary circuits, ensuring fast, vibration-proof, and maintenance-free wiring.

Benefits & Advantages

1. High-Performance Switching: Rated for 115A and 55kW, ideal for demanding motor and load switching applications.
2. Global Versatility: Features a wide-range AC/DC coil (220-240V) suitable for international deployment and different control voltages.
3. Fast & Reliable Wiring: Utilizes spring-loaded terminals (Cage Clamp) for the control and auxiliary circuits, drastically reducing wiring time and providing a secure, vibration-proof connection.
4. Modular System Integration: Seamlessly integrates with the Siemens SIRIUS components (like overload relays, auxiliary switches) for simple, compact, and complete load feeder setups.
5. IE3/IE4 Motor Ready: Designed to meet the requirements for switching modern, highly efficient IE3 and IE4 motors under the new AC-3e utilization category.

Function

The Siemens 3RT1054-2AP36 functions as a robust power contactor designed to safely and reliably switch electrical loads, primarily three-phase AC motors. It connects the motor to the power supply upon coil energization and disconnects it upon de-energization. The integrated auxiliary contacts provide status feedback and interlocks for complex control circuits and automation systems.
