Selection Guide
Use the table below to select the correct SKKT module for your application:
| Parameter | SKKT106/14E | SKKT106/16E ✓ | SKKT106/18E | SKKT132/16E |
|---|---|---|---|---|
| IT(AV) | 106 A | 106 A | 106 A | 132 A |
| VDRM/VRRM | 1400 V | 1600 V | 1800 V | 1600 V |
| Recommended Use | 380 V AC systems | 380–480 V AC ✓ | High-line 480 V+ | Uprated current |
| Package | SEMIPACK® 1 | SEMIPACK® 1 | SEMIPACK® 1 | SEMIPACK® 1 |
Rule of thumb: Select VDRM ≥ 2× peak line voltage. For 380 V AC (537 V peak), SKKT106/16E (1600 V) provides a safe 3× derating margin.
