Siemens 3RT1066-6AS36 Power Contactor, 300A, 160kW, 500-550V AC/DC Coil Original Brand New

Product Overview: Siemens 3RT1066-6AS36 SIRIUS Power Contactor

The Siemens 3RT1066-6AS36 is a robust, 3-pole SIRIUS power contactor designed for reliably switching motors and other loads up to 300 Amps (AC-3e/AC-3 rated) and a maximum power of 160 kW at 400 V. Part of the highly successful SIRIUS 3RT series, this contactor is built for demanding industrial applications requiring high operational reliability and long service life.

It features a versatile, wide-range 500-550 V AC (50-60 Hz) / DC conventional operating mechanism coil, ensuring compatibility with a broad range of control voltages and power systems globally. The main circuit connections are designed for robust busbar mounting, while the control and auxiliary circuits utilize convenient screw terminals for easy and secure wiring.

Key Benefit & Advantages

• High Performance: Safely switches high-power loads with an AC-3e/AC-3 rating of 300 A and motor power up to 160 kW.
• Global Versatility: The wide-range $500\text{–}550\text{ V}$ AC/DC coil simplifies inventory and is ideal for systems with variable or high control voltage requirements.
• Reliable Operation: Designed for high mechanical and electrical endurance, typical of the SIRIUS industrial controls range.
• Simplified Main Wiring: Robust Busbar connections on the main circuit simplify installation in motor control centers (MCCs) or large panel builds.
• Comprehensive Signaling: Integrated 2 NO + 2 NC auxiliary contacts allow for extensive monitoring and control circuit integration.

Function

The 3RT1066-6AS36 Power Contactor functions as an electromechanical switching device primarily for motor control. It is designed to:

1. Switch Motors: Connect and disconnect 3-phase electric motors safely under normal operating conditions.
2. Handle High Loads: Its high current rating is suitable for large-scale industrial machinery, pumps, ventilation systems, and other high-power equipment.
3. Provide Auxiliary Control: The 2 NO + 2 NC auxiliary contacts provide potential-free signals for interlocking, feedback, and control circuit logic (e.g., signaling motor ON/OFF status to a PLC or HMI).
