Product details

Spring Charging Mechanism: A spring is charged (compressed) either manually or electrically, and when released, it provides the force necessary to move the contacts. This mechanism ensures rapid and consistent operation, which is critical for safely interrupting the circuit.

Trip Coil: This coil is energized to release the charged spring, initiating the opening of the contacts and hence breaking the circuit.

Close Coil: Opposite to the trip coil, this coil closes the contacts, allowing the circuit to complete.

Arc Chute:


Although the arc is extinguished within the vacuum interrupter, an arc chute may be present to further manage and cool any residual arcs, directing the arc plasma away from the contacts.

3. Operation Phases:

Closing Operation:


The spring mechanism drives the moving contact towards the fixed contact inside the vacuum interrupter, closing the circuit and allowing current to flow.

The close coil is energized to initiate this process.

Opening Operation (Tripping):


When a fault is detected, the trip coil is energized, releasing the spring mechanism to quickly separate the contacts. This separation occurs within the vacuum interrupter.

The rapid separation of the contacts within the vacuum causes the arc to form and then extinguish almost instantaneously.

4. Advantages of the VCB Mechanism:

High Dielectric Strength: The vacuum interrupter provides excellent insulation and can withstand high voltages even when the contacts are very close together.

Long Operational Life: The absence of an arc, and minimal contact wear within the vacuum interrupter, leads to a longer operational life with minimal maintenance.

Fast Operation: The spring mechanism allows for rapid operation, essential for protecting electrical systems from faults.

No Gas or Oil: Unlike other types of circuit breakers, VCBs don’t use oil or gas, making them safer and more environmentally friendly.

5. Maintenance:

Low Maintenance: Due to the vacuum environment, there is minimal contact erosion, leading to a significantly lower requirement for maintenance.

Periodic Checks: However, periodic inspections are necessary to ensure the spring mechanism and other mechanical parts are functioning correctly.

Frequently asked by buyers
How does the spring charging mechanism enhance the VCB's operational speed?

The spring charging mechanism stores mechanical energy that, when released, moves the contacts rapidly and consistently, enabling the VCB to interrupt circuits within milliseconds which is critical for fault protection.

What role does the vacuum play in arc extinction within the VCB mechanism?

Vacuum provides an environment lacking gases or ionized particles to sustain an electrical arc, causing the arc formed during contact separation to extinguish almost instantaneously.

Can the VCB mechanism operate without electrical assistance for the spring charging?

Yes, the spring charging mechanism can be compressed manually or electrically, providing flexibility in operation and maintenance.

Why is an arc chute included if the vacuum already extinguishes the arc?

While the vacuum extinguishes the arc quickly, the arc chute manages and cools residual arc plasma, protecting contacts further and enhancing overall durability.

What makes VCB mechanisms environmentally friendly compared to other circuit breakers?

VCB mechanisms do not use oil or insulating gases such as SF6, which can be hazardous to the environment, making them safer and more eco-friendly for electrical installations.

How often should maintenance be conducted on the VCB mechanism?

Although VCB requires minimal maintenance due to reduced contact erosion, periodic inspections of the spring charging mechanism and other mechanical parts are recommended to ensure reliable operation.
