The SF6 Interrupter Pole 1250A, 33kV is an advanced high-voltage circuit breaker designed for reliable and efficient operation in electrical distribution networks. This interrupter utilizes environmentally-friendly sulfur hexafluoride (SF6) gas, providing superior performance in extinguishing electric arcs while ensuring longevity and reliability of the main contacts. Rated at 33 kV and a current capacity of 1250A, it operates smoothly at a frequency of 50Hz. The robust construction allows for a rated short time withstand current of 25kA for up to 3 seconds, making it ideal for high-demand applications. Its intelligent design features include a unique arc-extinguishing mechanism that utilizes the pressurized SF6 gas which, when the main contacts break, withstands the arc current effectively, preventing damage to the electrical system.

Rated Voltage- 12/24/36KV
Rated Current- 1250A
Rated Frequency- 50Hz
Rated Short Time Withstand Current- 25KA
Rated Duration of Short Circuit- 3sec
Rated SF6 gas pressure at 20 deg C- 1.5bar
Operational Features :
During breaking of the contacts, the puff of gas extinguishes the arc when the circuit breaker is in the closed position.
Due to movement of the piston, the gas is compressed. Firstly, the main contacts open and then the arcing contacts break the contact so as maintain a long life for the main contacts.
Due to this action, the compressed gas is released and it extinguishes the arc Valve opening during the closing operation, helps the piston to move swiftly.
