3TK2805-0AC2

The Siemens 3TK2805-0AC2 serves as an efficient contactor within the Breakers series. Specifically engineered for use in safety circuits, this component weighs 1.06 kg and operates effectively at an input voltage of 24 VAC. Its design incorporates five normally open contacts alongside one normally closed contact. The contactor is suitable for enabling (activating machine) and signaling circuits, which is critical in safety systems.

Versatile in its conductor connection capabilities, the 3TK2805-0AC2 can accommodate solid conductors with a cross-section of 1x (4 mm²) and 2x (1 to 2.5 mm²). This flexibility enhances its usability in various applications. The device does not support feedback input or position switch monitoring.

Operating effectively within an ambient temperature range of 0 to 40 degrees Celsius, it is also rated for a maximum allowable installation altitude of 1000 meters above sea level. The contactor can withstand humidity levels of up to 80% in both operating and storage conditions, provided they remain non-condensing. It is designed to function reliably at frequencies of 50/60 Hz, ensuring broad compatibility with numerous electrical systems.
