1 year warranty
The Siemens 3TK2806-0BB4 is a contactor safety combination designed for use in safety circuits with an enabling and signaling function. It features a contact configuration of 5 NO (normally open) plus 1 NC (normally closed) with a self-latching mechanism on contactor K1, and operates on a 24 V DC control supply. The device employs a dual-channel architecture suitable for use in machine safety applications such as emergency-stop circuits, protective door monitoring, and the safe disconnection of actuators in accordance with DIN EN / IEC 60204-1 in 'Autostart' mode. Built around standard SIRIUS contactor technology, it provides reliable positive-guided switching for safety-critical loads. This product is a phased-out part of the 3TK28 family; Siemens recommends the 3SK series as its functional successor.
