• Efficient Operation: The 110V AC coil ensures compatibility with common control circuits while the robust design handles demanding loads up to 7.5kW.

Function

The Siemens 3TB4222-0XG1 operates as an electromagnetically operated switch. When the 110V AC control voltage is applied to the coil, it generates a magnetic field that pulls the armature, closing the main power contacts. This action allows electrical current to flow to the connected load. When the control voltage is removed, a spring forces the contacts open, interrupting the power. The auxiliary contacts switch simultaneously with the main contacts, providing status indication or enabling control logic in the system.
