Ultimate Circuit Breaker for Enhanced Electrical Safety Solutions

Product Description

Product Description

circuit breaker 

The VS1-12 handcart-type indoor high-voltage vacuum circuit breaker is a three-phase AC 50Hz indoor switching device with a rated voltage of 12kV. It is used for control and protection in industrial and mining enterprises, power plants, substations, and electrical facilities, and is suitable for frequent operation scenarios. It adopts an integrated design of the operating mechanism and the circuit breaker body: it can be used as a fixed installation unit, or paired with a dedicated propulsion mechanism to form a single-handcart unit. The main circuit part can use an integrated sealed pole to achieve miniaturization, high reliability, and maintenance-free operation. It can be matched with middle-mounted handcart-type switchgear such as KYN28A-12(GZS), and can also be used with XGN fixed switchgear when in fixed installation mode.

Key Features & Benefits:

Fully Type-Tested Assemblies for Guaranteed Performance & Safety
Built-in Cybersecurity Features to Protect Critical Power Assets
Corrosion-Resistant Finish for Harsh Industrial & Marine Environments
Intuitive Human-Machine Interface (HMI) for Simplified Operation & Diagnostics
Remote Racking & Operation Capabilities for Maximum Operator Safety

From a single panel to a complete electrical distribution system, our Power Switchgear provides the intelligent control and steadfast protection required to manage modern electrical loads with confidence and precision.

Engineered for compact installations, our switchgear minimizes space requirements while delivering full-scale protection for modern, high-density facilities.

Maintenance-free busbar systems and sealed enclosures drastically reduce routine servicing and eliminate exposure to contaminants.

BASIC INFORMATION

Model Meaning

VS1-12

• VS: Indoor vacuum circuit breaker

• 1: Design serial number

• 12: Rated voltage (kV)

• T: Operating mechanism code (T = spring operating mechanism)

•  (first): Rated current (A)

•  (second): Rated short-circuit breaking current (kA)

Normal Operating Conditions

• Ambient temperature: Not higher than 40°C, not lower than -10°C (storage at -30°C is allowed);

• Altitude: Not exceeding 1000m (if higher altitude is required, the rated insulation level shall be increased accordingly);

• Relative humidity: Daily average not greater than 95%, daily average saturated vapor pressure not greater than 1.8×10 MPa;

• Seismic intensity: Not exceeding Grade 8;

• Environment: No fire, explosion, heavy pollution, chemical corrosion, or severe vibraton.

Special Notes:
If the installation site exceeds 1000m in altitude, or the ambient temperature/humidity exceeds the normal limits (or condensation occurs in high humidity), please consult us for customized solutions.
Note: We have launched products suitable for high-altitude areas (up to 4000m altitude), with rated current up to 1250A and rated short-circuit breaking current up to 31.5kA.
Product Technical Features
Superior Overall Performance of the Circuit Breaker
• The vacuum interrupter and operating mechanism are arranged front-to-back, connected as a whole via a transmission mechanism;
• Mechanical service life up to 30,000 operations.
Leading Vacuum Interrupter
• Middle-sealed ceramic vacuum interrupter;
• Copper-chromium contact and longitudinal magnetic field contact structure (a globally recognized advanced arc-extinguishing method).
Enhanced Insulation Casing
• Insulation casing is molded using APG new technology;
• Added inner ribs and reinforcing ribs improve insulation level and resistance to dynamic and thermal stability currents;
• The vacuum interrupter is installed inside the insulation casing, effectively preventing damage/ contamination from foreign objects, while significantly reducing the overall size of the circuit breaker.
Flexible & Convenient Operating Mechanism
• Spring energy storage type, with both electric and manual energy storage functions;
• When the circuit breaker operates, the energy of the energy storage spring is transmitted to the connecting rod mechanism via the output cam, then to the contact part;
• Advanced and reasonable buffer device: No rebound during opening, reducing opening impact and vibration;
• No adjustment required, minimal or no maintenance.
