Overview

ZW20-12 type outdoor high voltage AC SF6 circuit breaker is designed by our company as a circuit breaker sharing same cabinet.

Product Details

Product description

ZW20 series circuit breaker is the intelligent power distribution equipment which to solve the problems listed below:

1.Failures in T branch of overhead line cause the whole distribution off

2.Short circuits in the user end cause the whole distribution line off Working with our CMS-4000 distribution automation system to switch off the short circuit failures and earthing failures automatically. They can monitor the line status, realize remote control, telemeter, remote signal and remote regulating, and are the ideal intelligent distribution automation circuit breaker.
