Jwm6-11 Machine Tool Door Cut-off Switch

Jwm6-11 Machine Tool Door Cut-off Switch. Working Principle: It utilizes the thermal effect of a bimetallic strip. When a continuous overcurrent occurs in the circuit. he heat generated by the current causes the bimetallic strip to bend. When the bending reaches a certain degree, it triggers the mechanical mechanism to open the contacts and cut off the circuit. Characteristics: It features an inverse time delay response. This design allows motors to generate a brief inrush current during startup without tripping. specifically preventing equipment overheating and damage caused by long-term overloads.
