Key Features of F10 Auxiliary Switch

The Liyond Electric F10 auxiliary switch series is engineered with features that ensure precise control, adaptability, and reliable performance within medium and high-voltage switchgear. Its robust design and versatile configurations meet the demanding requirements of modern power systems.

The F10 series utilizes a direct drive mechanism, ensuring a robust and reliable connection between the switchgear’s operating mechanism and the auxiliary contacts. This design allows each contact section to directly respond to mechanical movement, achieving instantaneous and accurate signal conversion for critical control and interlocking circuits.

The F10 series exhibits excellent adaptability in terms of mechanical structure and installation:

Structural Forms: Supports different operational characteristics – “I” type (fast break/fast close action) and “III” type (slow break/slow close action), allowing selection based on required response speed.
Mounting Methods: Offers “W” type (horizontal) and “L” type (vertical) mounting methods, ensuring good compatibility with various switchgear designs and installation conditions.

The F10 auxiliary switch offers various contact configurations to adapt to different control needs:

Time-Delay Contacts: These contacts optimize complex control sequences by compensating for time lag in anti-bouncing relay operations. This ensures precise, error-free actions during transient changes, enhancing system stability and reliability.
Instantaneous Contacts: Providing immediate response, these contacts prevent sensitive electronic components, such as electronic counters, from damage due to prolonged energization. Their rapid switching characteristics extend component lifespan and reduce maintenance costs.

The F10 auxiliary switch is designed for demanding electrical environments and boasts impressive technical parameters:

Rated Voltage: Supports both DC (110V, 220V) and AC (220V, 380V) applications, ensuring broad compatibility.
Rated Current: Capable of carrying rated currents up to 10A (e.g., AC 220V, 380V), and features a rated maximum breaking current of up to 10A (AC 220V, cosΦ=0.4, t=20ms).
Electrical Life: Guarantees over 20,000 reliable operations, ensuring long-term stable running and reduced replacement frequency.

A major advantage of the F10 series is its support for customizable contact layer configurations, offering up to 10 layers of contacts for complex control schemes. Each contact module typically includes a pair of static contacts. This modularity, combined with available normally open (NO) and normally closed (NC) contacts, as well as specific time delay contact types (A, B, C, D, E), enables highly customized solutions.
