A universal circuit breaker is a device that provides electrical protection in a circuit. It is mainly used to control and protect electrical equipment in the circuit from faults such as overcurrent and short circuit.

The following is detailed information about the universal circuit breaker:

Basic principle: Universal circuit breaker through electromagnetic force, thermal response and electronic trigger and other mechanisms to achieve fault protection. When overcurrent or short circuit fault occurs in the circuit, the circuit breaker will quickly cut off the circuit to avoid equipment damage or fire.

Structure description: Universal circuit breaker is usually composed of circuit breaker body, rated current regulation device, heat release device, magnetic release device, trigger and operating mechanism. The circuit breaker body is the most critical component, which is composed of electromagnetic coil, contact and arc extinguishing device.

Breaking capacity: The universal circuit breaker can provide different breaking capacity according to different application requirements. It can break currents up to several thousand amps (A) and works well in high - and high-power systems.

Rated current and rated operating voltage: The rated current of A universal circuit breaker refers to the maximum continuous current that it can withstand, usually in amperes (A). The rated operating voltage refers to the circuit voltage range applicable to the circuit breaker.

Overload protection: When the load in the circuit exceeds the rated current, the circuit breaker will automatically cut off the circuit to prevent the equipment from overheating or short circuit.

Short circuit protection: When a short circuit fault occurs in the circuit, the circuit breaker will quickly cut off the circuit to protect equipment and personal safety.

Isolation function: The universal circuit breaker can also be used to isolate the circuit, convenient equipment maintenance and repair. Rebootable function: Some universal circuit breakers have a rebootable function, which can be re-connected by manual or automatic operation.

Application: Universal circuit breakers are widely used in industrial, commercial and residential electrical systems in various fields. They can be used to protect loads as diverse as motors, lighting, power lines, transformers and electronics. In general, the universal circuit breaker is a powerful, safe and reliable electrical protection device, by monitoring the current and fault in the circuit, to provide overload and short circuit protection to protect the normal operation of electrical equipment and personal safety
