FK10 Auxiliary Contact Switch For Circuit Breaker | Liyond

Liyond's FK10 series auxiliary contact, functioning as an essential auxiliary switch in circuit breaker control circuits, is primarily used for control conversion circuits in auxiliary electric circuits of AC/DC vacuum contactors. It also functions as an auxiliary contact in other electrical appliances, electromagnetic switches, and contactors. Its contacts are isolated from the outside, enabling normal operation in dusty environments.

Adaptable Design and Customizable Delay

The FK10 auxiliary contact offers adaptable configurations, including options for normally closed and normally open contacts. Design choices include "I" type with connector (for chassis trucks) or "II" type without (for earthing switch interlock). The FK10 series can be customized with delay contacts to meet specific operational requirements.

Robust Performance in Diverse Environments

Designed for reliable performance, the FK10 auxiliary contact operates effectively up to 3000m altitude, within -40°C to +40°C ambient temperature. Relative humidity must be below 95% daily and 90% monthly. It requires installation free from frequent vibration or bumping, and environments clear of dust, smoke, corrosive/flammable air, vapor, or salt fog.
