Max. speed according to EC type−examination certificate (for higher speeds contact the manufacturer)
The transition from the state without braking torque to the steady braking torque is not without
delay. The engagement times are valid for switching on the DC side with a spark suppressor
( (^ 31)). The diagram shows the delay during engagement t

Disengagement time
The disengagement time is not influenced by DC or AC switching operations.
