Application
|
| |
NF-CW moulded case circuit breaker is available in three ranges, standard, hi- break. The performance of the NF-CW MCCB range is the result of extensive design & development-utilizing AAD accredited test station. The current
limiting action of NF-CW MCCBs provides low values of let-through energy. Full information for this and time/current characteristic curves are both available on request to provide more information.
