Siemens SIRIUS 3RT1066-2AP36 Power Contactor, 300A, 160kW, AC/DC 220-240V, S10, Busbar, Spring-Loaded Terminal Original Brand New

Overview

The Siemens SIRIUS 3RT1066-2AP36 Power Contactor is a high-performance, 3-pole switching device engineered for controlling electric motors in industrial applications. As part of the modular SIRIUS 3RT1 series, this contactor offers exceptional reliability and a compact design, making it a cornerstone for efficient motor feeders and control panels. Rated for 300 A (AC-3e/AC-3) and a power output of 160 kW at 400 V, it is ideal for medium to high-power motor switching tasks.

This specific model features a universal AC (50-60 Hz) / DC coil with a control supply voltage (Uc​) of 220-240 V, providing flexibility and simplifying inventory for systems using both AC and DC control voltages. Its main circuit uses a robust busbar connection, while the control and auxiliary circuits are equipped with reliable spring-loaded terminals for fast, vibration-proof, and maintenance-free wiring.

Benefit

• High Performance: Safely switches motors up to 160 kW, meeting both AC-3 and the new energy-efficient AC-3e categories.
• Universal Control: Wide-range AC/DC coil (220-240 V) reduces product variation and stocking requirements.
• Reliable Connections: Busbar main circuit connection for high current and robust power distribution, complemented by vibration-proof spring-loaded terminals for auxiliary wiring.
• Fast Integration: Pre-installed 2 NO + 2 NC auxiliary contacts simplify control circuit design and reduce assembly time.
• Modular SIRIUS System: Seamlessly integrates with other Siemens SIRIUS components, such as overload relays and circuit breakers, for complete motor feeder solutions.
