The SF6 Interrupter Pole 1250A 11KV is the ideal solution for medium voltage switchgear applications, designed to offer reliable and efficient operation under high electrical stress conditions. With a rated voltage of 12KV and a current rating of 1250A, this interrupter pole is engineered specifically for durability and performance in demanding environments. Featuring advanced SF6 gas technology, it utilizes a gas-insulated switchgear design that significantly enhances operational safety and reliability. The SF6 gas acts as both an insulator and an arc-extinguishing medium, ensuring minimal risk of electrical failure. This interrupter pole is built to withstand short circuit currents of up to 40KA for 3 seconds, ensuring your system remains operational even under fault conditions. Its design effectively allows for a longer life span of contact components by controlling the sequence of interruptions, thus optimizing the lifecycle of your electrical installations.

The rated voltage is 12KV.
SF6 gas serves as both an insulating medium and an effective arc extinguishing agent during electrical interruptions.
The main contacts open first, causing piston movement that compresses gas, followed by the arcing contacts breaking the circuit to enhance the lifespan of the main contacts.
The arc is extinguished by the puff of compressed SF6 gas released during the breaking of contacts, ensuring efficient operation.
Yes, it can withstand a short-time current of 40KA for a duration of 3 seconds.

SF-6 Interrupter Pole
Rated Voltage- 12KV
Rated Current- 1250/2500/3150A
Rated Frequency- 50Hz
Rated Short Time Withstand Current- 40KA
Rated Duration of Short Circuit- 3sec
Rated SF6 gas pressure at 20 deg C- 2.5bar
Operational Features :
1) During breaking of the contacts, the puff of gas extinguishes the arc when the circuit breaker is in the closed position.
2) 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 to maintain a long life for the main contacts.
3) Due to this action, the compressed gas is released and it extinguishes the arc.
