Key features

Integrated Chassis Truck Racking: Enables smooth insertion and withdrawal within KYN28A-24 switchgear panels, establishing visible contact isolation for operating safety.

Prevent Phase Breakdown: Utilizes high-strength insulating cylinders to enclose vacuum interrupters, eliminating contamination risks and reducing maintenance frequency.

10,000-Cycle Mechanical Endurance: Built with a modular spring operating mechanism capable of AC/DC charging, ensuring stable long-term performance up to 31.5kA breaking.

Seamless Retrofit for 24kV Switchgear: Standard contact arm distance and pin logic allow direct drop-in replacement across various indoor distribution network substations.

Superior Arc Extinguishing Stability: High-vacuum interrupters combined with optimized contact geometry deliver faster current interruption compared to standard circuit breakers.

Product Q&A

Q:What structure type is used for the primary pole assembly on this VSG-24 model?

This VSG-24 model utilizes insulating cylinders to house the primary vacuum interrupters, ensuring accessible component layout and reliable phase-to-phase insulation performance in 24kV switchgear enclosures.

Q:Is this breaker compatible with standard KYN28A-24 withdrawable switchgear?

Yes. The chassis truck, pin dimensions, contact arm center distances, and secondary socket logic are designed to match standard 24kV withdrawable switchgear structures such as KYN28A-24.

Q:What control voltages are supported for the spring charging motor and trip/close coils?

Standard operating voltages are AC/DC 110V and AC/DC 220V. Alternative auxiliary voltages (DC 24V or DC 48V) can be customized based on station control specifications.

Q:Does the breaker include interlocks to prevent mis-operation during racking?

Yes. Built-in mechanical interlocks prevent the chassis truck from being racked in or out while the circuit breaker is closed. The breaker can only be operated when locked in either the Test or Service position.

Q:What parameters should be provided to confirm compatibility for a replacement order?

Please specify: Rated voltage (24kV), rated current (e.g., 1250A), short-circuit breaking capacity (e.g., 25kA/31.5kA), phase distance (mm), contact arm diameter, control circuit voltage, and Single Line Diagram (SLD).
