3TD Mechanical Interlocking Contactor
CJX1 3TD Mechanical Interlocking Contactor
APPLICATION:
The 3TD series exchange contact device is suitable in exchanges 50Hz or 60Hz, the voltage as for 660V, the nominal current to the 630A power circuit, for the long-distance range and the control motor connection and breaking, contact device's control circuit has the exchange (AC) and the cocurrent (DC) two kinds. Two contact device addition mechanical interlocking organization, the composition reversible contact device, most suits in the elevator electric circuit as well as needs electrical and the machinery dual interconnection electric circuits. The contact device may conveniently with the JRS series hot overload relay docking composition electric motor starter. Contact device's characteristic and the mounting dimensions to equate 3TB which, 3TF, the 3TD contact device produces in Germany Siemens.SPECIFICATIONS:
