The secure screw terminals make installation and wiring straightforward and dependable.

Key Features & Benefit

• High Switching Capacity: The 95A AC-3 rating is perfect for switching heavy motor loads, preventing damage and ensuring smooth operation.
• Robust & Durable: Built to Siemens’ rigorous quality standards, the 3RT7046-1AN20 offers a long mechanical and electrical service life, reducing maintenance costs.
• Easy & Secure Installation: Screw terminals provide a strong, reliable connection for both power and control wiring, minimizing the risk of loose contacts.
• Space-Efficient Design: The compact Size S3 profile allows for high-density panel layouts, optimizing valuable cabinet space.
• Global Compatibility: Operates with a standard 220 VAC, 50/60 Hz coil, making it suitable for a wide range of global industrial applications.
• Comprehensive Range: As part of the Siemens SIRIUS family, it integrates seamlessly with other Siemens components like overload relays and auxiliary contacts, offering a complete motor control solution.

Function

The Siemens 3RT7046-1AN20 contactor’s primary function is to act as an electrically-controlled switch for power circuits. It is typically used for:

• Switching Motors: Starting, stopping, and reversing three-phase electric motors.
• Resistive Loads: Controlling heating elements and other resistive loads.
• Distribution Panels: Serving as a reliable switching element in power distribution systems.

When the 220 VAC coil is energized, it creates a magnetic field that pulls the main contacts together, allowing current to flow to the connected load. When the coil is de-energized, the contacts open, interrupting the power circuit.
