General data
1)
Opening time on instantaneous short-circuit release with
ETU15B = 85 ms.
2)
Make-time through closing solenoid for synchronization purposes
(short-time excited) 50 ms.
3)
Maintenance means: replace main contact elements and arc chutes (see
Operating Manual).
4)
Use of releases from –20 °C
5)
ETU76B with graphics display can be used up to max. 55 °C.
6)
Minimum interval between 2 switching operations.
7)
3-pole switching with switching capacity N and S: 45/h.
8)
For switching capacity H: 1600 A to 70 °C.
9)
The main contacts of size I circuit breakers with switching capacity H can
only be replaced at the factory.
