Siemens 3RT1054-2AM36 Power Contactor 115A, 55kW, AC/DC 200-220V, 3-Pole, 2NO+2NC, Spring-Loaded Terminal Original Brand New

Overview

The Siemens 3RT1054-2AM36 is a high-performance power contactor designed for reliable switching and control of electrical loads in industrial applications. Part of the SIRIUS 3RT series, this contactor is engineered for durability, efficiency, and safety. It features a robust design that can handle high currents and power, making it ideal for controlling motors and other electrical equipment.

Key Features & Benefit

• High Power Rating: With an AC-3e/AC-3 rating of 115 A and 55 kW at 400 V, this contactor is suitable for demanding applications involving large motors and machinery.
• Versatile Control: The contactor operates on a wide control voltage range (Uc) of 200-220 V, accommodating both AC (50-60 Hz) and DC power sources, which provides flexibility in different power systems.
• Enhanced Safety and Control: It includes built-in auxiliary contacts (2 NO + 2 NC), which are essential for interlocking, signaling, and creating complex control circuits, thereby improving operational safety and system automation.
• Efficient and Secure Connections: The main circuit is designed for busbar connection, ensuring high current capacity and a secure, low-resistance connection. The control and auxiliary circuits utilize spring-loaded terminals, which offer fast, reliable, and vibration-proof wiring without the need for constant retightening. This reduces installation time and maintenance effort.
• Compact and Robust Design: The 3-pole configuration is housed in a durable and space-saving enclosure, making it easy to integrate into control cabinets and electrical panels. Its conventional drive mechanism ensures a long mechanical and electrical service life.
• SIRIUS modular system: As part of the Siemens SIRIUS series, it is compatible with a wide range of accessories and other SIRIUS products, allowing for easy expansion and customization of control solutions.

Function

The Siemens 3RT1054-2AM36 contactor serves as a crucial component in industrial electrical systems. Its primary function is to remotely switch on and off electrical circuits, especially those with high power loads like motors, heating elements, and transformers.

When the control coil is energized, the main contacts close, allowing power to flow to the load. De-energizing the coil opens the contacts, safely interrupting the circuit. The auxiliary contacts provide feedback on the status of the main contacts (open or closed), enabling control systems to monitor and manage the operation of the connected equipment.
