Product Description

                                                          QSA Series Isolating Switch Fuse Set
Application:
QA Series Isolating Switch Fuse Set, QA and QP Series Isolating Switches (hereinafter referred to as "switch") are mainly used in the circuit of AC 50Hz(or 60Hz) and rated working voltage up to 660V. In the power supply and distribution circuit of large short-circuit current and low power factor, it can serve for master switch for manual infrequent operation, especially for mounting in the drawer type low-voltage complete equipment.

Normal Working Conditions
The ambient air temperature shall not exceed +40º C. The average value shall not exceed +35º Cwithin 24 hours. The lower-limit of ambient air temperature is -5º C.
The height above sea level for installing the switch shall not exceed 2000m.
When at max. Temperature of +40º C, relative air humidity shall not exceed 50%. Higher relative humidity such as 90% at the temperature of 20º C, is allowed under lower temperature. Special measure shall be taken against occasional condensation caused by temp. Change.
The pollution grade of environment for installing switch is 3.
The switch shall be vertically installed in the place without vibration or shock.
