What this part is
| Type | Miniature circuit breaker (MCB) |
|---|---|
| Rated current | 80 A |
| Trip curve | K |
| Poles | 3 |
| Breaking capacity (this part) | 25 kA |
Parts listed here share these values. Matching one value alone (for example the current) does not make a replacement.
Check before you substitute
- Breaking capacity (kA) at the same voltage and to the same standard (IEC 60898-1 or IEC 60947-2)
- Busbar type (pin or fork), terminal size and module width
- Accessories: auxiliary, shunt trip, locking
- Approval required on site (SASO, IEC, UL)
