4.5.2. Short delay protection (S)
4.5.3. Instantaneous protection (I)
32 ABW - Air Circuit Breaker
Protection against short-circuit (timed performance),
with feature of inverse time or defined time.
1. Current Isd
- Adjustment of range: (1.5-2-3-4-5-6-8-10-Off) xIr
2. Performance time tr
- The performance time is based on the current
of 10xIr
- Adjustment of range for inverse time:
(0.1-0.2-0.3-0.4)s
- Adjustment of range for defined time:
(0.05-0.1-0.2-0.3-0.4)s
3. The unit performs as per the greatest current
between the phases R, S, T and the neutral N.
4. The unit can also operate instantaneously by
means of the function ZSI.
