Product Description

Product Overview

The ZN63A(VS1)-12C is an indoor high-voltage vacuum circuit breaker designed for 12KV three-phase AC power systems. Featuring a side-mounted fixed installation structure, it excels in frequent operation and short-circuit current protection scenarios. Its integrated design and reliability make it ideal for fixed switchgear and customized power supply systems.

Key Features

1.Compact Side-Mounted Design: Integrated operating mechanism and breaker body, space-saving, and compatible with fixed switchgear.
2.High Operational Frequency: Engineered for frequent load current switching and short-circuit interruption, ensuring durability.
3.Modular Compatibility: Can be paired with dedicated propulsion mechanisms to function as a withdrawable unit, adaptable to ring network power supply, box-type substations, and non-standard systems.
4.Low Maintenance: Sealed structure minimizes environmental impact, ensuring long-term stability and reduced upkeep.

Applications

Industrial Power Protection: Power distribution systems in factories, mines, and substations for load control and fault isolation.
Grid Automation: Supports urban grid automation upgrades, enabling remote operation and smart monitoring.
Custom Power Solutions: Suitable for renewable energy microgrids, rail transit, and other tailored electrical infrastructure projects.

Specification

(The value can be customized according to customer's local demand!)

If you have any specific requirements for the parameters of the transformers, you can contact us . And then We assemble a dedicated team of account managers, technical engineers, and product consultants. Through on-site surveys and professional interviews, we identify your specific application scenarios (power, railway, mining), key technical parameters (voltage, capacity, protection class), and environmental requirements (temperature, humidity, outdoor conditions). We also clarify budget constraints and delivery timelines to ensure a perfect fit.
