Detailed Product Description

Automatic transfer switches YEQ1-63L series dual power automatic transfer switches (follow brief as setting) is one of adopted international technology developed by our company. The setting is suits for AC 50Hz, rated working voltage is 400V, rated current 6A-100A and under dual power supply system. It has over voltage, under voltage, lost phases protection function. The setting mainly used for hospital, shopping center, bank, and chemical industry, metallurgy, high building, military facilities. IEC 947-6-1(1998)Automatic Transfer Switch Electric Equipment

Ambient temperature: -5 - +40°C, and average temperature in 24 hours below +357deg;C (except for special orders).
Elevation of installation site: 2000m
Relative humidity: not exceeding 50% at the maximum ambient temperature of +40°C.
With lower temperature, higher humidity would be permitted, but the lowest average temperature in a month not exceeding 90% in that month, and giving consideration to the dews on the goods surface, which would appear due to temperature change.
Pollution protection: 3 grade
The breaker should be put in the place where there isn't any explosive medium and
conductive dust and no gas, which would corrode metal or destroy the insulation.

The voltage of the automatic controller and motor operation controller is AV220V.
The life of the switch (N-R-N) is 10000 times.
The minimum transfer time is 1.5~3s.

The transfer switch panel has two 1A fuses and one trinodal connection terminal.
The fuse is used to automatic controller short circuit protection, and the terminal is indicate the signal lamp connects into the controller box panel, and supply the power, the voltage is AC220V, current is 150Ma.
And 1 is common power signal lamp power, 2 is ready power signal lamp power.
