Product Description

 

Product Description

 

FN7 series Load break switch, generally comes with the spring mechanismfor switching ON & OFF the supply, however, option with vacuum circuitbreaker is also available. Of course, option with Vacuum circuit breaker iscostlier. Choice between these two totally depends on the customer. Loadbreak switch with vacuum circuit breaker is more reliable option.
