The ZN12-24 vacuum circuit breaker is an indoor high-voltage switchgear with a rated voltage of 24kV and three-phase AC 50Hz.which introduced the technology from German company， Its operating mechanism is a spring energy storage type, which can be operated by AC or DC, or manually. This circuit breaker is a reinforced insulation type, which meets the requirements of the use environment in Class II polluted areas. This circuit breaker has simple structure, strong breaking capacity, long life, complete operation functions, no explosion hazard, simple maintenance, suitable for control or protection switch of power plant, substation and other transmission and distribution systems, especially suitable for breaking important loads and frequently operated places. This product is in accordance with related requirement of GB1984, JB3855, DL403 and IEC standards.

CT68-24 vacuum circuit breaker is an indoor high-voltage vacuum circuit breaker, mainly used in distributed power systems, mines, petroleum, chemical industry, metallurgy, construction, transportation, coal mines and municipalities, as well as in the power supply and distribution systems of urban residential buildings and public facilities and other places. It is widely used to protect high-voltage power equipment from over-current, short-circuit, under-voltage and over-voltage, and can reliably guarantee the safe operation of power equipment. CT68-24 vacuum circuit breaker adopts fully enclosed structure (central type), has good waterproof and moisture-proof performance, and can work under harsh environmental conditions. It has good thermal stability of short-circuit full-load current, strong overvoltage capability and short-circuit breaking capacity. In addition, it can quickly connect wires, cables and other equipment to improve installation efficiency and make site installation and maintenance more convenient. Widely used at home and abroad, CT68-24 vacuum circuit breaker is a high-quality power equipment, known for its reliable performance, excellent quality and long service life.

VBI indoor high-voltage vacuum circuit breaker has reliable performance and is easy to install. It is the best choice for the control and protection of high-voltage transmission and distribution systems. The VBI-40.5 Floor Mounted Vacuum Circuit Breaker is a high-performance, medium-voltage switching device designed for reliable protection and control of electrical systems rated at 40.5kV. Utilizing advanced vacuum interrupter technology, it ensures efficient arc quenching, minimal maintenance, and a long operational lifespan. Ideal for power distribution networks, industrial plants, and substations, this breaker combines robust construction with user-friendly operation.

Application of IndoorsF6 Circuit Breaker SF6 circuit breakers are a perfect upgrade foraging power infrastructure,especially in situations where the insulation of motors and cables is sensitive to dielectric stress.Indoor SF6 circuit breakers.with their compact footprint and top-notch insulation performance,are right at home in space-constrained indoor substations and distribution rooms.They stand up well to frequent operation,ensuring the stable running of critical equipment and slashing maintenance downtime.Furthermore,their environmentally friendly characteristics make them an ideal fit for indoor locations with strict environmental requirements,helping to build a safer and more reliable power distribution network. LYHM4 medium voltage circuit breaker uses sulfur hexafluoride (SF6) gas as arc extinguishing and insulating medium. SF6 gas has smooth breaking characteristics, and there will be no interception phenomenon when breaking the current, and no operating overvoltage will occur. This excellent characteristic ensures that the circuit breaker has a long electrical life. And the impact on the equipment during operation, the dielectric level and thermal stress will not be affected.

Their compact dimensions and limited weights make the Power Cube type PB/F fixed parts the ideal solution for replacing fixed circuit breakers with withdrawabie circuit breakers, for retrofitting activities and for upgrading obsolete switchgear to the new Standards. The Power Cube type PB/F fixed parts are factory-assembled and tested and, where applicable, comply with IEC 62271-200 and IEC 62271-1 Standards. The fixed parts allow construction of arc proof switchgear - classification LSC2B-PM IAC BFLR or LSC2B-PM AFLR according to IEC 62271-200 (in accordance with IEC 62271 Standards for general characteristics).
