In case of short circuit, the magnetic field generated by large current (generally 10 to 12 times) overcomes the reaction spring, the release pulls the operating mechanism to act, and the switch trips instantaneously. In case of overload, the current increases, the calorific value intensifies, and the bimetallic sheet deforms to a certain extent to promote the action of the mechanism (the greater the current, the shorter the action time).

The sensitive components of the capacitive pressure transmitter measurement section adopt a fully welded structure, while the electronic circuit section adopts wave soldering and connector installation methods. The overall structure is sturdy and durable, with few faults. Compared to the vast majority of users, if sensitive components are found to malfunction, they are generally unable to repair themselves. Therefore, the manufacturer should be contacted to replace the entire component.
