QZJB600A Normal Closed DC Contactor
APPLICATION SCENARIOS
1. Safety protection: Normally closed contactors are often used in safety systems, such as emergency stop buttons, to ensure that power can be cut off immediately in an emergency.
2. Automation control: In some automated equipment, it is used to control the start and stop of the equipment to ensure that the equipment can be safely shut down under certain conditions.
3. Battery Management System: used to cut off power when the battery is overloaded or short-circuited to protect the safety of the battery and circuit.
