24kv indoor VCB

Youbian's high-quality 24kV indoor VCB is suitable for three-phase AC power systems with rated voltage of 7.2kV~24kV and frequency of 50/60Hz. We generally use it in many fields such as power plants, substations, petrochemicals, metallurgy, manufacturing, airports, residential areas, etc., for controlling and protecting electrical equipment. Especially suitable for situations where the operating frequency is low at rated current or multiple short-circuit currents are required,

Usage environment

a) Air temperature: maximum temperature:+40 ℃; Minimum temperature: -25 ℃

b) Humidity: Monthly average humidity of 95%; Daily average humidity of 90%

c) Altitude: Maximum installation altitude: 2500 meters

d) There is no obvious corrosive or flammable gas, steam or other pollution in the ambient air

e) No frequent and severe vibrations

Note: The short-circuit breaking current and rated current can be customized according to customer needs.

Key Features

The main components of this VCB are sealed with international brand sealing poles, vacuum arc extinguishing chambers, and main conductive circuit components, which have stronger impact resistance, dust prevention, and anti condensation performance.

The 24kV indoor VCB has strong environmental adaptability and can significantly reduce operating and maintenance costs.

The integrated design of the operating mechanism and the circuit breaker body has been verified through type testing.

The 24kV Indoor VCB has an E2 level electrical lifespan and an M12 level mechanical lifespan, ensuring long-lasting and reliable performance.
