In low-voltage power distribution systems, molded case circuit breakers (MCCBs) are core components for overload and short-circuit protection, and their reliability directly impacts equipment safety and personnel protection.
If any abnormality is found during testing, the power must be immediately cut off to check the wiring or replace the water valve relay.
Shafts must withstand the tension of springs in the operating mechanism, the contact pressure when the contacts close, and the preload force when the housing is assembled.
In power electronics, new energy, rail transportation, and high-end industrial equipment, high-voltage capacitors serve as key energy storage and filtering components, and their performance directly affects system stability and safety.
In power systems, molded case circuit breakers play a crucial role in protecting circuit safety. When an overload or short-circuit fault occurs, it must complete detection, judgment, and disconnection actions within a very short time to prevent equipment
Sealing gaskets are key components to prevent water vapor penetration and are usually made of elastic materials such as silicone or fluororubber.
