The FK10-II-22 auxiliary switch is designed for auxiliary circuit control, electrical interlocking, and signal transmission in medium voltage switchgear, vacuum circuit breakers (VCB), earthing switches, electromagnetic switches, and contactors.
It is widely used in power distribution systems to ensure accurate status indication, reliable control logic, and safe interlocking operations.
High Reliability
Manufactured with high-quality materials and precision contacts, ensuring stable performance in long-term operation under power system conditions.
Sealed & Dust-Proof Design
Isolated contact structure effectively protects internal components from dust and contaminants, suitable for switchgear cabinets and harsh industrial environments.
Compact Structure
Small size with a simple and practical design, allowing flexible installation and easy integration into existing switchgear layouts.
Long Mechanical & Electrical Life
Durable contact materials provide extended service life, reducing maintenance frequency and total operating costs.
Standardized & Customizable
Standard mounting dimensions enable compatibility with vacuum circuit breakers, isolating switches, and other MV devices.
Custom contact configurations are available upon request.
Multi-Functional Use
Supports indication, control, signaling, and interlocking functions, meeting diverse requirements of medium voltage power equipment.

1.Ambient air temperature: -40℃~+40℃
2.The altitude of the installation place is not more than 2000m above sea level.
3. Temperature and humidity conditions are as follows: the average value of relative humidity measured in 24H does not exceed 95%, the average value of water vapour pressure measured in 24 hours does not exceed 2.2Kpa, the average value of monthly relative humidity does not exceed 90%, and the average value of monthly water vapour pressure does not exceed 1.8Kpa, taking into account the condensation that occurs on the surface of the product due to temperature changes.
4. Acceleration is not greater than 15m / square second
5. The air is not obviously polluted by dust, smoke, corrosive and combustible gases, vapours or salt spray.
