Product overview
The LN2-40.5 indoor high-voltage SF6 circuit breaker is an indoor device in the AC 50Hz three-phase system and can be used for protection and control in industrial and mining enterprises, power plants, and substations (stations). It can be used in places with frequent damage, and can also be used as a contact circuit breaker and a capacitor bank circuit breaker.
LN2-40.5 type is equipped with CT1017, 19 or conjoined spring operating mechanism. LN2-40.5 type SF6 circuit breaker can be equipped with GBC-40.5, JYN1-40.5, XGN17-40.5 switch cabinet and also can be equipped with KYN61-40.5, KYN10-40.5 Metal-enclosed removable high-voltage switch cabinet.
The circuit breaker operating interface is located on the operating mechanism panel. It can directly observe the status of the circuit breaker and operate the circuit breaker. It is suitable for various installation locations.
The integrated design of the mechanism and arc extinguishing system achieves coordination between the operating mechanism and the load, reduces the closing work, improves operating characteristics, and enhances reliability.
Adopting reinforced insulation design, it can meet the requirements for use in high altitude, condensation and Class II pollution environments.
The breaking capacitor current can reach 800A.
Operating environment conditions
1. The altitude does not exceed 2000m;
2. Ambient air temperature: upper limit: +40°C; lower limit: -10°C in general areas, -25°C in alpine areas
