Protective Elements
Please be aware of the meaning of the two delay timers.
t load Off (Pickup Delay): After this time expires, the load is no longer
diversified.
t Max Block (Release Delay): After the starting condition is fulfilled (e.g.:
breaker switched on manually), the “CLPU.enabled” signal will be issued for
this time. That means for the duration of this time, the tripping thresholds of the
overcurrent protection can be desensitized by means of adaptive parameters
(please refer to the Parameters section). This timer will be stopped if the
current falls below 0.9 times of the threshold of the load inrush detector and
remains below 0.9 times of the threshold for the duration of the settle time.
This Notice applies to protective devices that offer control functionality only!
This protective element requires, that a switchgear (circuit breaker is assigned
to it. It is allowed only to assign switchgears (circuit breaker) to this protective
element, whose measuring transformers provide measuring data to the
protective device.
