Siemens SIRIUS 3RT1055-6AP30 Power Contactor, 150A, 75kW (400V), AC/DC 220-240V Coil, 3-Pole, Busbar Original Brand New

Overview: High-Performance Power Contactor

The Siemens SIRIUS 3RT1055-6AP30 power contactor is a heavy-duty, 3-pole switching device engineered for controlling electric motors and other resistive loads in industrial and commercial applications. Part of the renowned Siemens SIRIUS modular system, this contactor (Size S6) offers reliable performance, a robust design, and seamless integration into modern electrical systems.

It is rated for a high operational current of 150 A (AC-3e/AC-3) and a motor power of 75 kW at 400 V. A key feature is its flexible control: it operates with a conventional AC/DC wide voltage range control supply of 220-240 V. The main circuit connections utilize busbar technology for high-current, robust power connections, while the control and auxiliary circuits use secure screw terminals. This model is supplied without integrated auxiliary contacts, allowing for maximum customization with add-on auxiliary switches.

Benefit

• High Reliability: Exceptional switching performance and contact reliability characteristic of the SIRIUS family.
• Space Efficiency: Compact design (Size S6) simplifies panel building and saves valuable cabinet space.
• Global Standard Compliance: Approved for worldwide use (e.g., IEC and UL/CSA standards), making it ideal for international projects.
• Versatile Control: The wide-range AC/DC coil (220-240V) simplifies stock-keeping and offers flexibility in control system design.
• Robust Power Connections: Busbar connection on the main circuit ensures high-quality, high-current power transfer.
• IE3/IE4 Ready: Optimized for use with high-efficiency motors.

Function and Application

The 3RT1055-6AP30 functions as a remotely operated switch for high-current loads. It is primarily used for:

1. Switching 3-Phase Motors: Starting, stopping, and controlling large industrial motors (up to 75 kW).
2. Resistive Load Switching: Controlling heating elements, lighting circuits, and other resistive loads in high-power applications (AC-1 rating up to 185 A).
3. Industrial Automation: Essential component in motor starters, control panels, and load feeders across all sectors (e.g., manufacturing, HVAC, water treatment).
