Circuit Breakers for Use in Particular Applications
Upgrade your electrical equipment by using products suitable for your particular application.
If it is considered as proper when the standard MCCB/ELCB is not chosen to use in a special characteristic of the load, the special breaker is needed.
Isolation Switches DSN
On creating an isolation switch (DSN) by omitting the overcurrent tripping device of a MCCB, it can be used as a switching device with high operating capacity.
