Output Tripping Characterstics

The tripping characteristic can be set to Slow or Fast as a common parameter for all channels.

Tripping characteristic

Slow / Fast

selectable, factory setting is Fast

Tripping delay

typ.

1.1s

For all channels in Slow mode at 1.5x nominal current

typ.

0.22s

For all channels in Fast mode at 1.5x nominal current

typ.

2ms – 1.1s

For CH1 and CH2 in short circuit

max.

10ms

For CH3 to CH8 in short circuit

The following curves show the let-through current areas, which are located to the left of the curves, and the tripping areas,
which are located to the right of the curves.
