| Operation feature |
I≤1.05IR (motor protection I≤1.0IR ), more than 2h's in-operation (when In≤63A, more than 1h's in-operation) |
|||
| I≥1.3IR (motor protection I≥1.2IR ), less than 2h's in-operation (when In≤63A, less than 1h's in-operation) |
||||
| Operative time (s) | Time setting value (s) | 12, 60, 80, 100 | ||
| Characteristic curve | TR =(2IR/ I)²×IR | |||
| Time accuracy | ±10% | |||
Note: when setting current, instantaneous current value Ii should bigger than short delay current setting value Isd, should bigger than long delay setting value IR, that is IiIsd IR. If long delay, short delay and instantaneous setting values are overlapping,priority should be:
instantaneous release→short time delay release → long time delay.
