VS1-12/630A-25KA side-mounted indoor high voltage vacuum circuit breaker
Product Introduction
Product name: VS1-12 side-mounted indoor vacuum circuit breaker
Category: high voltage components
Product introduction: VS1-12 side-mounted vacuum circuit breaker is an indoor high-voltage switchgear. It is suitable for three-phase power systems with a rated voltage of 12 dry volts and a frequency of 50 Hz. It is used as a protection and control appliance. It is especially suitable for places that require frequent operation under rated current or multiple interruption of short-circuit current.
Overview of VS1-12 side-mounted indoor vacuum circuit breaker
VS1-12 side-mounted vacuum circuit breaker is an indoor high-voltage switchgear. It is suitable for three-phase power systems with a rated voltage of 12 dry volts and a frequency of 50 Hz. It is used as a protection and control appliance. Due to the special nature of the vacuum circuit breaker, it is especially It is suitable for places that require frequent operation under rated current, or break short-circuit current many times.
VS1-12 case-mounted vacuum circuit breaker adopts fixed installation and is mainly used for fixed switchgear. The interrupter can be used alone, but also can be used for ring network power supply, box-type substation or various non-standard power supply systems.
