Product Description
LW28(with indicator bar )Universal Changeover Switch with Good Performance with Ce Certificate
Scope of applicationLW28 series universal switch is mainly used for AC 50Hz, rated voltage 380V and below, DC voltage 220V and rated current 160A electric circuit. It can be used for control and conversion of manual and infrequent switching on or off circuit. It can also directly control three-phase asynchronous motor and be used as master control and circuit measurement. The products are widely used, instead of all kinds of national formal switches, they can be used as circuit control formal switches, test equipment switches, motor control switches, master control switches, and welding machine conversion switches.
Meet the standard: The main circuit conversion switch and direct control switch conform to GB14048.3-2001.
The switch for command control conforms to GB14048.5-2001.
Normal working conditionsThe ambient air temperature does not exceed + 40 C, and the average temperature within 24 hours does not exceed + 35 C.
The lower limit of ambient air temperature should not exceed - 5 C.
The altitude of the installation site shall not exceed 2000 m.
When the maximum temperature is + 40 C, the relative temperature of air does not exceed 50%. Higher relative humidity can be allowed at lower temperatures, such as up to 90% at 20 C. Special measures for occasional condensation due to temperature changes are taken.
classificationAccording to the use, there are main circuit conversion switch, direct control motor conversion switch and main command control and measurement conversion switch.
According to the mode of operation, there are positioning, self-replicating and positioning self-replicating.
According to the contact system, the positioning switch has 1-12 sections (only 8 sections in 63A), the self-replicating switch has 1-3 sections, and the direct control switch mainly has 1-6 sections.
According to the angle, it can be divided into 30 degree, 45 degree, 60 degree, 90 degree and so on.
According to the shape of the panel, there are square panel, rectangular panel and circular panel (only 20A).
There are eight types of knobs: R type, I type, F type, B type, S type, L type, P type and K type.
