(1) Selection of overload protection device The overload protection device of the soft start device should choose a thermal overload relay with overload protection, phase failure protection and temperature compensation functions. When selecting, the working current of the motor should be within the range of the setting current of the thermal element. For equipment that is easy to be overloaded during operation, the rated current value of the motor should be close to the lower limit of the setting current range of the thermal element. (2) The electrical wiring and component arrangement of the low-voltage soft-start cabinet The general electrical wiring of the low-voltage soft-start cabinet is shown in Figure 2. The electrical components in the cabinet are arranged in the order shown in the figure, so that the main wiring is short and does not cross, which is convenient for the connection of copper bars. The soft starter is installed on the right side of the contactor and is not affected by the heating of other components. The distance between the soft starter and the side wall of the control cabinet and other components is required to be 2100mm, which is convenient for the soft starter to dissipate heat. (3) Selection of bypass contactor At the end of the soft start, the motor has been running at the rated voltage, so the AC contactor can be selected according to the rated current of the motor to meet the requirements. It should be noted that when wiring the cabinet, the soft starter and the contactor should be connected in the same phase, and do not connect the wrong phase sequence. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #softstarter #motorsoftstar #softstarters #softstartechnology #solidstatesoftstarter #functionsmartsoftstarter #ZJSHUYI #intelligentmotorsoftstarter #chinashuyi
