Generator Circuit Breaker (GCB) Panel

The Generator Circuit Breaker (GCB) compartment provides on-line isolation in the main power circuit between the generator and generator transformer, utilizing either a vacuum or SF6 draw-out circuit breaker. The metal-enclosed switchgear compartment houses both control and protection system components, ensuring reliable operation.

Powergear has also designed mobile cubicles equipped with line-side and neutral-side bus bars, along with the Generator Circuit Breaker and metering/protection equipment. These mobile GCB cubicles are mounted on a trailer, making them ideal for short-term mobile power plants.

Vacuum Circuit Breaker (VCB)

The 11/22/33KV Vacuum Circuit Breaker (VCB) Panel is designed for transformer protection, ensuring reliability and safety. Manufactured to meet strict industry standards, these panels are known for their superior quality and cost-effectiveness. VCB panels are available from original equipment manufacturers (OEMs) for new installations, repairs, retrofits, and upgrade projects.

How VCB Panels Work

A VCB panel is a type of circuit breaker where the arc quenching occurs in a vacuum environment. This technology is best suited for medium voltage applications. Although it can be used for higher voltages, it is not commercially viable.

Key Features & Materials

• Utilizes CuCr (Copper Chromium) for electrical contacts, ensuring high performance.
• Requires minimal maintenance compared to other relay control panels.
• Ideal for industrial, commercial, and power distribution applications.

Why Choose VCB Technology?

VCB is one of the most trusted and reliable current interruption technologies in medium voltage switchgear. Engineers continue to enhance its efficiency and durability, making it a preferred choice for modern electrical systems.
