Materials and help contact terminals

Terminal material nylon (PA66), where V0 flame retardant grade, at the same time, do not contain any harmful halogen, flame retardant performance is superior, safe, environmental protection.Other commonly used materials and thermoplastic polyester (PBT), and to cope with perforated reflux technology and use of liquid crystal polymer (LCP).
Function theory:
When the motor overload, input more current than the rated current of electrical, thermal relay the heat element will due to excessive current flows through the fever.Cause bending.Through the mechanical structure of the internal drive the output switch contact.Achieve the goal of "overload" output.Auxiliary contact of "NC" contact group can series in the control circuit of power lines (with "stop" button series), once the motor overload, the auxiliary contact "NC" contactor will cut off the control circuit of power supply, make the machine stop running.Auxiliary contact of the "NO" contact group can pick up alarm device (e.g., alarm indicator light), once the motor due to overload and stop operation, gives the cause of the motor to stop - "overload".
Help contact terminal:
Terminal heat element, usually by the thermal expansion coefficient of different metal materials.Double thermal element if heated metal materials, because of the different expansion coefficient, bending will occur.Work when the hot components in series in the main loop of the circuit (such as motor starter motor power supply circuit in).Up and down two rows of each have three terminals, each hot components connect between the two terminals on a, a total of three components, respectively in series in article 3 of the motor power input line.The auxiliary contact, usually a normally open (NO), a normally closed (NC) contact.Used for the starter motor control circuit.
