RP5S Automatic Transfer switch
Automatic Transfer Switches Model and Meaning
Description
RP5S series dual-power automatic transfer switch is newly developed micro household power transfer switch.
The switch is mainly used for testing whether normal or spare power is normal or not.
When the normal power is abnormal the spare power works at once which ensure the continuity reliability and safety of powersupply.
The product is specifically designed for household orbit-type installation and specifically used in PZ 30 power distribution box.
RP5S series automatic transfer switch is suitable for the emergency power supply system with 50/60Hz rated voltage 400Vandcurrent100A.
It is compact in structure reliable in transfer.convenient in installation and maintenance.and has long life expectancy.
Widely used in various occasions where continuous power failure is not allowed.
It can be operated both electrically and manually.RP5S is composed of RTSE and the controller.
RP5S complies with requirements of low-voltage switchgear and control gear specified by IEC 60947-6-1andIEC 60947-3； function equipment and transfer switch equipment.

Normal working conditions and instatlation conditions
♦ Ambient air temperature
The upper limit is not over+40°C.the average value of 24his not over+35°C and the lower limit is not less than-5°C
♦ Above sea level
The installation site should not be over 2000m above sea level
♦ Atmosphere conditions
When the highest temperature is^40°Cs the relative humidity of the atmosphere of installation site should not be over 50%.
At lower temperature， higher relative humidity is allowable，for example， the temperature+25°Cf the relative humidity90%.
Special measures should be taken to deal with the occasionally generated condensation on the surface of the product due to temperature cn anges.
