3.4 Rated data (dimensioning data) electrical data
3.5 Switching times
Engagement time
The transition from a brake-torque-free state to a holding-braking torque is not free of time lags.
❚ The engagement times apply for DC switching with a spark suppressor.
- Spark suppressors are available for the rated voltages.
- Connect the spark suppressors in parallel to the contact. If this switching is not admissible for safety
reasons (e.g. with hoists and lifts), the spark suppressor can also be connected in parallel to the
brake coil.
- Circuit proposals: 29
❚ The engagement times are approx. 10 times longer with AC switching .
- Connection: 29
