Function / Application

The 3RT2916-2BL01 is used to introduce a controlled time delay after the coil of the contactor is de-energized (OFF-delay or break delay). This is critical in applications such as:

1. Sequential Operations: Ensuring motors, pumps, or valves shut down in a specific order.
2. Process Delay: Maintaining power to certain components for a short duration (e.g., fans for cooling) after the main load is switched off.
3. Preventing Chatter: Stabilizing the control circuit and preventing contactor coil ‘chatter’ or premature dropout.
