Dropout
The greater dropout differential (= | pickup threshold – dropout threshold |) of the following 2
criteria applies:
Dropout differential
95 % of the pickup value
Minimum absolute dropout differential
Protection-class current transformer 15 mA sec. (I
rated
= 1 A) or
75 mA sec. (I
rated
= 5 A)
Instrument current transformer 0.5 mA sec. (I
rated
= 1 A) or
2.5 mA sec. (I
rated
= 5 A)
Circuit-Breaker Supervision
Position supervision via circuit-breaker auxiliary contacts
For 3-pole CB tripping 1 input each for make contact and break contact
i
i
NOTE
The circuit-breaker failure protection can also work without the circuit-breaker auxiliary contacts stated.
Auxiliary contacts are required for circuit-breaker failure protection in cases where the current flow is
absent or too low for tripping (for example with a transformer or a Buchholz protection).
Times
Pickup time, in the case of an internal start
Pickup time, in the case of an external start
< 1 ms
< 5 ms
Typical dropout time < 15 ms
Dropout time via circuit-breaker auxiliary contact
