PRODUCT DESCRIPTION
SIEMENS 3RT5964-6A - Electronic Star-Delta Timer Block
The SIEMENS 3RT5964-6A is an electronic timer block specifically engineered for integration with SIRIUS 3RT5 series contactors. This accessory provides precise star-delta (wye-delta) motor starting functionality, managing the sequential switching of contactors to reduce inrush current during motor startup. It is designed for direct front-mounting onto compatible contactors, facilitating compact and reliable control circuit implementation in industrial motor control centers and machinery.
