Types of VCB Spare Parts
We are leading VCB Spare Part Manufacturers in India we offer a variety of VCB (Vacuum Circuit Breaker) spare parts that are used to sustain an ideal performance and uninterrupted work of the industrial power systems. Our products include the basic interrupter parts, working mechanism, control and protection parts, and panel accessories and serve a wide variety of industrial needs.
- Core Breaker Components
a) Vacuum Interrupters (VIs): Vacuum interrupters centered in the heart of the VCB interrupt the electrical current in a vacuum which guarantees arc extinction and high-voltage isolation.
b) VCB Pole Assembly: It is a structure that accommodates the interrupters and contacts to offer mechanical support and alignment to facilitate smooth operations.
c) Epoxy Insulators/Spouts: High-quality epoxy used as insulators offers electrical protection to the poles, contacts, and connections, and increases their longevity.
d) Tulip Contacts/ Shower Contacts: These connections make sure that the electrical circuits are accurately made and broken in the VCB to achieve stable performance. - Operating Mechanism Spares
a) Spring Charging Motor: This drives the spring mechanism in order to store the energy which would be used to effectively close the breaker.
b) Tripping & Closing Coils: Electromagnets used in operating the door (tripping) and closing the breaker to make sure it operates accurately under various conditions.
c) VCB Mechanism: The entire mechanical unit, gears, and leverages make the process of charging, tripping and closing of the breaker easy. - Control & Protection Spares
a) Auxiliary Switch: Status feedback of control circuits (open/closed) is provided to allow monitoring and automation of the VCB.
b) Relays: Circuits are guarded by thermal, magnetic or even static relays that detect fault and cause the breaker to operate when necessary.
c) TNC Switch (Trip-Neutral-Close): A tripping, neutral and close switch that is operated manually and fitted in control panels.
d) PT Fuses & CT Units: Current and Potential Transformers help in proper metering and protection of the circuit, whereas the Fuses guard against the overcurrents. - Panel & Trolley Spares
a) VCB Trolley: A portable system in which breakers can be easily inserted and removed on the control panel, to enable the maintenance.
b) Copper Busbars: Copper bars with high conductivity give a good conduit on which current can flow through the panel.
c) Access Panels and General Panel Spares: Cover, additional panel parts and accessories make sure that there is correct assembly, safety and easy maintenance.
