F11-Y delay quick action auxiliary switch
Detailed introduction:

1、 Application characteristics

The closing opening time (metal short-circuit time) of high-voltage circuit breaker is a key time parameter affecting the breaking capacity of circuit breaker, which has been solved well at home abroad. F11-y delay quick action auxiliary switch with delayed closing contact solves the scheme of closing opening time of circuit breaker, the principle is simple reliable. It meets the requirement of self-defense function of circuit breaker by improving auxiliary switch. The F11 auxiliary switch has universal applicability to (hydraulic mechanism / pneumatic mechanism), is an excellent practical scheme at present.

2、 Conditions of use

a. Ambient air temperature: - 40 ℃ ~ + 40 ℃;

b. Altitude: no more than 3000m;

c. The humidity conditions are as follows: the average value of relative humidity measured within 24h does exceed 95%; the average value of water vapor pressure measured within 24h does exceed 2.2kpa; the average value of monthly relative humidity does exceed 90%; the average value of monthly water vapor pressure does exceed 1.8kpa;

d. The vibration acceleration shall be greater than 15m / S;

e. The surrounding air is obviously polluted by dust, smoke, corrosive combustible gases, vapor salt spray.
