Protective functions

9.1.6.1 Basic protective functions

The basic protective functions of the trip unit are ensured without additional auxiliary voltage. The required energy is supplied by the



circuit breaker's internal energy transformers.

To evaluate the currents, the electronic system of the trip unit calculates the r.m.s value.

The individual functions are parameterized according to the types via:

- rotary coding switch (ETU745 - 748)
- electronic data transfer (ETU776) via:

- the BDA
- the PROFIBUS-DP / MODBUS

- the control board (ETU776)

Overload protection – L-tripping

The current setting I

defines the maximum continuous current the circuit breaker can carry without tripping. The long-time delay t

determines the maximum duration of an overload without tripping.



The tripping characteristic is an I

t characteristic. Some trip units can be switched over to an I

t characteristic.





(page 9-15)

Short-time delayed short-circuit tripping – S-tripping

On trip units ETU745 - 776, tripping due to the short-circuit current I

can be delayed by the time t

This provides selectivity for short-circuit protection in switchgear with several grading levels.

The delay time 0.02 sec. is not an I

t function.



The motor protection function is activated in this position.

For settings t

>0.4 sec., the maximum possible setting I

is reduced automatically according to the frame size:



Frame size II

: 20 kA



Frame size III : 30 kA

The setting "OFF" for trip units ETU745 and ETU776 is provided to deactivate the short-time delayed short-circuit protection.

If the zone selective interlocking (ZSI)



(page 9-15)

is used and the ZSI module is set to "S" or "S+G" the adjusted delay time t

is auto-

matically set to 50 ms provided that in the event of short-circuit the circuit breaker does not receive a blocking signal from a downstream
circuit breaker. In this case regardless of the adjusted t

value the circuit breaker will trip after 50 ms.

If a blocking signal exists the adjusted delay time tsd is valid. For safety reasons after 3 s the blocking signal is terminated.

Some trip units can be switched over to an I

t-characteristic.

(page 9-16)

Setting values for I

ETU745 - 748

= (0.4 / 0.45 / 0.5 / 0.55 / 0.6 / 0.65 / 0.7 / 0.8 / 0.9 / 1.0) x I

ETU776

= (0.4 - 1.0) x I

(given in Amps)

Setting values for t

ETU745 - 748

= 2 / 3.5 / 5.5 / 8 / 10 / 14 / 17 / 21 / 25 / 30 sec. (at 6 x I

)

ETU776

= 2 - 30 sec. (at 6 x I

)

Setting values for I

ETU745 - 748

= (1.25 / 1.5 / 2 / 2.5 / 3 / 4 / 6 / 8 / 10 / 12) x I

ETU776

= 1.25 x I

- 0.8 x I

(given in Amps)

Setting values for t
