1 Overview
HY series reversing switch (hereinafter referred to as
switch) is suitable for AC 50Hz (or 60Hz) circuits with
rated operating voltage up to 380V and with rated
operating current up to 20A, and is primarily used to
directly turn on/off a single squirrel cage induction motor
for start, run, stop, and reverse rotation.
This series of products comply with the standard
GB14048.3 "low-voltage switchgear and controlgear -
Switches,
disconnectors,
switch-disconnectors
and
fuse-combination units".
The product has obtained 3C certification certificate.
The normal operating conditions of the switch are as
follows:
a) The ambient air temperature does not exceed +40° C
and the lower limit of its ambient air temperature is -5° C,
and the average temperature within 24 hours does not
exceed +35° C.
b) The altitude of the installation site does not exceed
2000m.
c) Atmospheric
relative
humidity
at
the
switch
installation site does not exceed 50% when the ambient
temperature is +40℃, and a higher relative humidity is
allowed at a lower temperature, such as 90% at 20° C.
Special measures are taken for condensation generated
occasionally due to temperature changes.
