SCHNEIDER ELECTRIC LAD9ET3S - Electronic Timer Block
This component is an electronic timer block from the SCHNEIDER ELECTRIC TeSys D series, engineered for direct integration with TeSys D contactors. It provides a precise, adjustable time delay function specifically for controlling star-delta motor starting sequences, facilitating a controlled transition from star to delta configuration. This module is critical for industrial motor control applications requiring reduced inrush current and controlled torque during motor acceleration.
Technical Specifications:
