Siemens 3RT1076-6AS36 SIRIUS Power Contactor 500A, 250kW, 500-550V UC Original Brand New

Overview

The Siemens 3RT1076-6AS36 is a high-performance SIRIUS 3RT1 power contactor designed for demanding industrial applications. This robust 3-pole contactor is engineered to handle a substantial current rating of 500 A for AC-3e/AC-3 applications, making it suitable for controlling motors up to 250 kW at 400 V. It features a versatile conventional drive and is compatible with both AC (50-60 Hz) and DC control voltages from 500 V to 550 V (Uc). The main circuit uses a convenient busbar connection, while the control and auxiliary circuits utilize secure screw terminals for easy and reliable wiring.

Key Benefit

• High-Current Handling: Safely controls high-power loads with a 500 A current rating.
• Versatile Power Control: Ideal for managing motors up to 250 kW.
• Flexible Application: Operates on both AC and DC control voltages.
• Reliable Connections: Features busbar for main circuit and screw terminals for control/auxiliary, ensuring secure and durable connections.
• Integrated Auxiliary Contacts: Includes 2 NO (Normally Open) + 2 NC (Normally Closed) auxiliary contacts for enhanced control and signaling capabilities.

Function

A power contactor is an electrically controlled switch used for switching an electrical power circuit. The Siemens 3RT1076-6AS36 functions by using an electromagnet to close the main contacts, allowing high current to flow to a load such as an electric motor. The integrated auxiliary contacts can be used for various control functions, such as feedback signaling to a PLC (Programmable Logic Controller) or interlocking with other components. Its conventional drive mechanism ensures reliable operation in various industrial environments.
