Siemens 3RT1076-6XF46-0LA2 Power Contactor, 500A, 250kW, 110V DC Original Brand New

Product Overview

The Siemens 3RT1076-6XF46-0LA2 Power Contactor from the SIRIUS 3RT1 family is a robust, 3-pole switching device engineered for high-performance motor control and general industrial applications. Rated for up to 500 A (AC-3e/AC-3) and 250 kW at 400 V, this contactor is specifically designed for environments demanding extended rated conditions, such as railroad applications (certified to IEC 60077). It features a wide voltage range 110 V DC electronic coil for reliable operation, a built-in PLC input (24-110 V DC), and integrated auxiliary contacts (2 NO + 2 NC).

Features & Benefit

• High Performance: Safely switches high currents up to 500 Amps and controls motors up to 250 kW, ideal for heavy-duty industrial loads.
• Railroad Certified (IEC 60077): Designed to meet the stringent shock, vibration, and temperature requirements of railway and similar extended-rated condition applications, ensuring extreme reliability.
• Electronic DC Coil: Offers a wide operating voltage range (0.7-1.25 x Uc​) and lower holding power consumption compared to conventional coils, leading to high-speed, chatter-free switching.
• Integrated PLC Compatibility: Includes a dedicated 24-110 V DC PLC input, simplifying direct interfacing with modern control systems like Siemens SIMATIC PLCs without intermediate relays.
• Convenient Connections: Features Busbar connections for the main power circuit, ensuring a secure and high-capacity connection, and standard screw terminals for the control/auxiliary circuit.
• SIRIUS Modular System: Full compatibility with the Siemens SIRIUS range of thermal overload relays and accessories for complete motor feeder solutions.

Application
