Overview of 12KV 630A 1250A 1600A 2000A 2500A 3150A VCB VS1 Indoor High Voltage Vacuum Circuit Breaker VS1-12KV/1250-25KA Fixed

12KV 630A 1250A 1600A 2000A 2500A 3150A VCB VS1 Indoor High Voltage Vacuum Circuit Breaker VS1-12KV/1250-25KA Fixed is a type of circuit breaker where the arc quenching medium is a high vacuum. Unlike older breakers that used air, oil, or SF6 gas to extinguish the electrical arc, a VCB utilizes the superior dielectric properties of a vacuum to rapidly extinguish the arc when the contacts separate, thereby interrupting the current flow and protecting the electrical system.

This circuit breaker handles 12 kilovolts. It comes in different current ratings: 630 amps, 1250 amps, 1600 amps, 2000 amps, 2500 amps, and 3150 amps. It’s a vacuum circuit breaker. That means it uses a vacuum to interrupt the electrical current. This type is called a VCB. Its model is VS1-12KV/1250-25KA Fixed. It’s built for indoor installations. You fix it in place; it’s not movable. The main part is the vacuum interrupter. This component stops the current flow quickly. It does this when a fault happens. It also works for regular switching operations. The vacuum inside provides strong insulation. This insulation is called dielectric strength. It helps the breaker handle high voltages safely. It also prevents electrical arcs from forming. This design makes the breaker reliable. It requires less maintenance than older types. The breaker can interrupt high fault currents. The “25KA” in the model name means 25 kiloamperes. That’s its breaking capacity for faults. This breaker protects electrical systems. It stops overloads and short circuits. It ensures equipment safety. It prevents damage to the network. The operating mechanism is spring-powered. Springs store energy for switching actions. This mechanism is dependable. It works fast for opening and closing. The breaker frame is sturdy. It holds all parts securely. Terminals connect the cables. These terminals are clearly marked. The breaker fits standard switchgear panels. Installation follows common practices. Operators control it manually. It also works with remote control systems. Monitoring options are available. These options show the breaker’s status. The design focuses on safety. It protects people working nearby. It ensures stable power distribution.
