Siemens 3RT1476-6SF36 Power Contactor AC-1, 690A / 690V, 3-Pole, Auxiliary Contacts, F-PLC 24V DC Input Original Brand New

Overview

The Siemens 3RT1476-6SF36 power contactor is designed for robust industrial performance. Supporting AC-1 690A at 690V, this 3-pole contactor ensures reliable operation in demanding electrical environments. With a flexible F-PLC 24V DC input and electronic auxiliary contacts (2 NO + 2 NC), it delivers precision control for your automation systems. Its main circuit supports busbar connection while control and auxiliary circuits use screw terminals for secure and efficient wiring.

Benefits & Advantages

• High Power Switching: Rated for 690 A (AC-1), making it suitable for high-current heating loads, isolation, and general switching applications in heavy industry.

• Flexible Control: The electronic wide-range coil (96-127V AC/DC) simplifies inventory and offers stable operation under voltage fluctuations.

• PLC Integration: The dedicated F-PLC input 24 V DC allows for direct and secure connection to safety-oriented programmable logic controllers.

• Durability: Exceptional mechanical and electrical service life, minimizing maintenance and maximizing uptime.

• Easy Integration: Clear busbar connection for the main power circuit and standard screw terminals for control wiring ensure straightforward installation.

Function & Application

The SIRIUS 3RT1476-6SF36 functions primarily as a heavy-duty switching device in industrial electrical systems.

• Primary Function: Making and breaking connections to high-current, non-motor (AC-1) loads like large heating elements, resistance furnaces, lighting systems, and capacitor banks.

• Secondary Function: Acting as a reliable power isolation device or switch for machine tool control and distribution panels.

• Safety Integration: The F-PLC input enables its use in circuits requiring safety-related switching functions monitored by a safety PLC.
