Engineered for High Performance and Durability

With mechanical endurance exceeding 10,000 operations and high breaking capacities, our Vacuum Circuit Breakers ensure consistent performance in demanding environments. The spring operating mechanism delivers quick opening and closing (within 80 ms and 60 ms, respectively), reducing downtime and enhancing system reliability. Designed to meet stringent safety and operational standards, these VCBs protect assets and personnel across a variety of power distribution setups.

Designed for Versatile Power Distribution

These Vacuum Circuit Breakers support rated currents up to 2000A and voltages up to 12kV, making them suitable for a wide spectrum of applications in power distribution systems. Their robust construction, advanced arc-quenching technology, and high insulation levels offer optimal safety and operational efficiency, even under high short-circuit or overcurrent conditions.

Convenience and Safety Built-in

Our VCBs feature both automatic and manual trip options and multiple auxiliary/control voltages (110V, 220V, 240V AC/DC), ensuring adaptability to various control schemes. They also include comprehensive overheating protection, low energy consumption, and powder-coated surfaces for additional longevity. The floor-mounted, compact design (700 x 600 x 1450 mm) fits seamlessly into standard installations, while high IP ratings support use in harsh environments.

FAQ's of Vacuum Circuit Breakers:

Q: How does the spring operating mechanism improve the performance of vacuum circuit breakers?

A: The spring operating mechanism provides reliable and rapid opening and closing of the breaker contacts (with closing time of 80 ms and opening time of 60 ms). This ensures the circuit breaker responds swiftly to faults, minimizing equipment damage and increasing overall system safety.

Q: What are the key benefits of using this vacuum circuit breaker in power distribution systems?

A: Key benefits include high interrupting (up to 31.5kA) and making capacity (63kA), low energy consumption, high operating efficiency (>98%), minimal maintenance needs, and a long mechanical life of over 10,000 operations. Features such as arc quenching, overheating protection, and high insulation levels enhance safety and performance.

Q: When should I use a fixed versus a draw-out type connection for the VCB?

A: Draw-out type connections are preferred in installations requiring frequent maintenance, replacement, or inspection, as the breaker can be easily removed without disturbing the busbars. Fixed-type connections are ideal for applications where the breaker stays in place for long periods and minimal disconnection is expected.

Q: Where are these vacuum circuit breakers typically installed?

A: These VCBs are commonly installed in medium-voltage power distribution systems such as substations, industrial complexes, and commercial buildings, supporting applications up to 12kV. Their floor-mounting design and three-phase compatibility suit a wide range of electrical infrastructure projects.

Q: How does the vacuum interrupter contribute to the breaker's performance and safety?

A: The vacuum interrupter extinguishes the arc formed during current interruption by creating a vacuum environment, ensuring rapid arc quenching, reduced contact erosion, and high dielectric strength. This leads to safer operation, minimal maintenance requirements, and longer equipment life.

Q: What environmental conditions can these circuit breakers withstand?

A: These circuit breakers operate efficiently between -10C and +55C, can be stored at -25C to +70C, and function at altitudes up to 1000 meters. They also handle humidity levels below 95% RH and are protected by IP4X/IP55 enclosures, ensuring durability in both indoor and challenging environments.

Q: What is the process for tripping and closing the VCB, and what controls are available?

A: The circuit breaker can be operated both automatically (in response to faults) and manually, using a spring mechanism. It supports auxiliary and control supply voltages of 110V, 220V, and 240V (AC/DC), allowing integration with diverse control schemes. The trip and close operations are fast and reliable, ensuring seamless protection of the power system.
