Re: NW 50 H1 Breaker not closing.

Hello @alungalsanthosh ,

 

A few questions :

 

What is exactly the state of the front indicator ?

- Discharged

- Charged "Not OK"

- Charged OK

 

What happens if you try charging the mechanism by handle ?

 

Alternately, did you investigate the following points :

- interlocking ?

- MN shunt trip coil not powered ?

- Trip indicator not resetted ?

 

Thanks,

Christian
