| HR6 series Fuse Type Isolating Switch
|
|
|
|
Application
This series can be used in the circuit of rated voltage up
to 690V,AC 50Hz(or 60Hz),and conventional free air heating current up
to 630A. It is applicable for distribution circuit of high short-circuit
current and motor circuit, serving for power switch, isolating switch,emergergency
switch as well as circuit protector.Generally,it can not be used for
directly switching of single motor and is for use indoors. This switch
can be mounted in the cabinet as well as on the panel of cabinet, providing
new low-voltage electruc element for complete set of electric control
equipment. |

Normaol Working Conditions
1.The ambient air temperature shall exceed +40¡æ, The average
value shall not exceed +35¡æ within 24 hours,The lower-limitof ambient
air temperature is -5¡æ.
2.Generally, height above sea level shall not exceed 2000m.For higher
height above sea level.consult with manufacturer.
3.When at max.temperature of +40¡æ,relative air humidity shall not exceed
50%. Higher relative humidity such as 90% at the temperature of 20¡æ.if
allowed under lower temperature. Special measuer shall be taken against
occasional condensation caused by temp.change.
4.Pollution grade:pollution grade of ambient environment of switch is
3.
5.Switch shall be vertically installed in a place without obvious vibration
or impact vibration.

Structural Features
This switch is composed of two parts: base and switch cover.The
base is mounted with contct and arc-extinguishing system. The fuse body
is mounted on the switch cover, directly serving for moving contact
blade. The base and switch cover are made of plastic through pressing.Therefore,
it is of small volume, light weight and beautiful outline, etc.
