What mechanical lifespan will I get from this unit?

This timer relay has a mechanical lifespan of up to 30 million switching cycles, so it delivers long-term performance.

What does the device's star-delta changeover mode do?

It's an operating system that prevents excess current use during motor starting operations by initially energising the motor in a star configuration to limit harmful inrush current.
