Overview

The Siemens 3TB4211-0XN2 is a high-performance AC contactor designed for reliable switching of electrical loads. It’s built for demanding industrial applications, offering a size 1 frame for a compact footprint. This contactor is specifically engineered for use with a 220V AC coil and operates effectively on both 50Hz and 60Hz frequencies.

Key Benefit

• High Performance: With a rated current of 16A and a power rating of 7.5kW at 400V, this contactor is capable of handling significant electrical loads.
• Versatile Application: Suitable for a wide range of applications, including motor control and other general-purpose switching tasks.
• Integrated Safety: The included 1 normally closed (NC) auxiliary contact provides a crucial connection for safety circuits and status feedback.
• Simple Installation: Features screw connections for straightforward and secure wiring.

Function

This contactor serves as an electrically controlled switch for a power circuit. When the 220V AC coil is energized, it closes the main power contacts, allowing current to flow to the connected load. The integrated NC auxiliary contact is useful for interlocking circuits, providing feedback on the contactor’s status (e.g., indicating when the main circuit is open).
