Specifications

Description

1.Mini outdoor high voltage vacuum circuit breaker
2.Vacuum arc technology
3.Safe, easy operation
4.Imported epoxide resin

Main features:

  1. SPV-12/24 circuit breaker applies vacuum arc theory.
  2. This circuit breaker is a three-phase separated box. It can meet the usage in high altitude, high temperature and humid areas and avoid any phase to phase fault and earth fault because of small phase spacing.
  3. The shell of the circuit breaker applies stainless steel which is corrosion resistant for forever use.
  4. The insulation of overall encapsulating pole and current transformer applies imported outdoor epoxide resin, which is resistant to low temperature, ultraviolet radiation and ageing with long life span.
  5. The compact disconnecting switch which is small and light can be installed; the stainless steel and integrative disconnecting switch and lightning arrester can also be installed.

Main technical data of circuit breaking:

NO.
