a) Adjustment of range in N and A type units:
(0.4~1.0) xIn
- Iu: (0.5-0.6-0.7-0.8-0.9-1.0) xIn
- Ir: (0.8-0.83-0.85-0.88-0.9-0.93-0.95-0.98-1.0) xIu
b) Adjustment of range in the P and S type units:
(0.4~1.0) xIn
- Ir: (0.4-0.5-0.6-0.7-0.8-0.9-1.0) xIn
2. Performance time tr
- The performance time is based on current of 6xIr
- Adjustment of range: (0.5-1-2-4-8-12- 16-20-Off)s
3. Start of timing
- It occurs when the current exceeds 1.15xIr
4. The unit performs as per the greatest current
between the phases R, S, T and the neutral N.
