Product Description

Product Description

 

VS1-24 series solid-sealed indoor vacuum circuit breaker is a three-phase power system indoor high-voltage switchgear with a rated voltage of 24kV and a frequency of 50Hz. Because of the vacuum circuit breaker, it is used to protect and control electrical appliances. Special advantages are particularly suitable for frequent operation requiring rated current or multiple short-circuit currents.

VS1-24 series solid-sealed indoor vacuum circuit breaker is a fixed installation, mainly used for fixed switchgear. The circuit breaker can be used alone, or used for ring network power supply, box transformer or various non-power supply systems.
