3TD Reversing Contactor Combinations
Description
3TD Reversing Contactor Combinations are suitable for frequency of 50/60Hz, rated insulation voltage up to 690 ~ 1000V, rated operational current 9A ~ 400A at rated operational voltage 380V under AC - 3. They are mainly used for controlling the forward and reverse rotation. They comply with IEC947, VDE0660, GB14048.
Operating Conditions
● The altitude of the site of installation does not exceed 2000 meters above sea levels. ● The ambient air temperature: -25 ~ +55°C ● Relative humidity does not exceed 50% at +40°C and 90% at +25°C ● Atmospheric conditions: the air does not contain any explosive medium, corrosive gases and conductive dust. ● Never be shocked and vibrated obviously. ● Never be wetted by rain and snow.
Features
● It is a Combinations consisting of two same type sets of 3TF AC contactors, between which one is interlocked by another through a mechanical device. ● The mechanical interlocking device does not affect the acting time of a single set of AC contactors. ● The conducting wires of the main circuit and auxiliary circuit have been connected. (The products without connection can also be suplied.) ● Compact in size, reliable in interlocking. ● The overload relays 3UA can be mounting directly on the 3TD (up to 3TD42).
