Key features

Embedded Pole Technology: APG-cast solid embedded poles protect vacuum interrupters from impact, dust, and condensation, ensuring high insulation stability in MV switchgear.

2000A High Thermal Capacity: Optimized primary tulip contact assembly reduces contact resistance and heat generation during heavy continuous current delivery.

31.5kA Short-Circuit Breaking: Delivers robust system protection with 31.5kA short-circuit breaking capacity and M2 class mechanical endurance over 10,000 operations.

210mm Phase Spacing Standard: Designed with a 210mm phase-to-phase distance to integrate directly into standard 800mm-wide KYN28A-12 indoor switchgear cabinets.

Modular Front-Mounted Mechanism: Integrates a compact spring operating mechanism at the front, offering easier routine inspection and faster component maintenance.

Product Q&A

Q:What are the key rated parameters for this VSG-12 vacuum circuit breaker model?

This model features a 12kV rated voltage, 2000A rated current, 31.5kA rated short-circuit breaking current, and a standard 210mm phase-to-phase distance.

Q:Is this VCB configured as a drawout type for KYN28A-12 switchgear?

Yes, it comes equipped with a standardized chassis truck (handcart), secondary plug assembly, and primary contacts, designed for smooth racking into KYN28A-12 or similar 800mm-wide air-insulated switchgear cabinets.

Q:Does the breaker structure use solid insulation (embedded pole) or insulating cylinder?

This specific unit utilizes APG resin embedded poles, housing the vacuum interrupter directly inside the epoxy casing to prevent environmental contamination and increase insulation capability.

Q:Can control coil voltages, motor operating voltage, and auxiliary switches be customized?

Yes, products are built to order. Operating voltages for the spring-charging motor, shunt release, and closing coils (e.g., AC/DC 110V, 220V, or 24V), as well as auxiliary contact configurations (F10 type), can be configured to match your project schematic.
