Siemens 3RT1075-2AV36 SIRIUS 3-Pole Power Contactor, 400A, 200kW, AC/DC Coil, Spring-Loaded Terminal Original Brand New

Overview

The Siemens 3RT1075-2AV36 is a high-performance SIRIUS series power contactor designed for demanding industrial applications. Engineered for reliability and efficiency, this 3-pole contactor is rated for AC-3e/AC-3 operation up to 400 A and 200 kW at 400 V. Its versatile AC (50-60 Hz) / DC control coil, with a wide voltage range of 380-420 V, ensures compatibility with various control systems.

The inclusion of two normally open (NO) and two normally closed (NC) auxiliary contacts provides enhanced flexibility for control and signaling circuits. The main circuit features a busbar connection for robust power distribution, while the control and auxiliary circuits utilize convenient and secure spring-loaded terminals, simplifying installation and maintenance.

Key Benefit

• High Performance: Capable of handling significant loads up to 400 A and 200 kW, making it ideal for heavy-duty motor control and industrial power switching.
• Versatile Control: The wide-range AC/DC control coil (380-420 V) provides flexibility and reduces the need for multiple contactor variants.
• Enhanced Safety and Control: Equipped with 2 NO + 2 NC auxiliary contacts, allowing for complex interlocking, status signaling, and control functions.
• Reliable Connections: The busbar main circuit connection ensures a secure and high-current carrying capacity, while spring-loaded terminals on the control and auxiliary circuits provide vibration-proof and maintenance-free connections.
• Compact Design: Part of the SIRIUS modular system, this contactor offers a space-saving design for efficient panel layout.

Function

The Siemens 3RT1075-2AV36 power contactor is primarily used for switching and controlling electric motors and other resistive or inductive loads in industrial automation, machinery, and power distribution systems. It is activated by a conventional control circuit voltage (380-420 V AC/DC) which energizes the coil, closing the main power contacts to supply power to the load. The integrated auxiliary contacts can be used for various purposes, such as:

• Interlocking: Preventing simultaneous operation of two or more devices.
• Feedback: Providing status signals to a Programmable Logic Controller (PLC) or other control systems.
• Alarm Circuits: Triggering alarms in case of specific operational states.
