BSBC7-150 Specification Notice 1. Using spring washers to prevent loose screws when installing contactors. 2. The torque range for tightening screws is specified in the accompanying table. Exceeding the maximum torque may cause the product to break. There is no polarity requirement for the main contact and the lead of the control coil of this contactor. 3. The main contacts and control coil leads of this contactor are non-polarized, meaning there are no polarity requirements. 4. Products equipped with an economizer feature a built-in reverse surge absorption circuit, eliminating the need for...

BSBC7-150 Specification resistance of the coil will increase, which will increase the product’s closed voltage, may cause excess of rated closed voltage. In this case, the following measures should be taken: Reduce the load current, limit the duration of continuous power or use coil voltage higher than the rated suction voltage. 10.For resistive load, the rated main contact rating shall apply, and for inductive load (L load) with L/R>1 millisecond, an inrush current protection device shall be connected to the inductive load in parallel. 11.The drive circuit power of the product coil must be greater...
