3TK1910-3B SIEMENS

The 3TK1910-3B is a 2nd auxiliary switch block designed for lateral mounting on contactors, offering flexible installation options on either the left or right side. This auxiliary switch block enhances the functionality of contactors by providing additional switching capabilities for control circuits and signaling. It features a combination of one normally open (NO) and one normally closed (NC) contact, enabling versatile integration into various automation and control systems. The NO contact closes when the contactor is energized, while the NC contact opens, providing distinct signals for interlocking, monitoring, or control purposes. This auxiliary switch block is particularly useful in applications where additional contacts are needed beyond those provided by the main contactor. Its compact design ensures minimal space consumption within the electrical panel. The 3TK1910-3B auxiliary switch block is compatible with a range of Siemens contactors, ensuring seamless integration and reliable performance. It is built with high-quality materials to ensure durability and long-term operational stability. This auxiliary switch block is an essential component for expanding the control capabilities of contactor-based systems.
