Circuit Breakers

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. This helps to prevent hazardous arcing or metal melting caused by the heat of an overloaded circuit, or the electric shock that could result from a short circuit.

Application Field: A PR21-62F-15.0A-32851-1-V rated current 15A circuit breaker is widely used in a variety of applications such as home appliances, industry machines, electric vehicles, and power grids, etc. It can also be installed in circuit panels and cabinets for for providing over-current protection on circuits.

Working Principle: A PR21-62F-15.0A-32851-1-V rated current 15A circuit breaker is designed with a bimetallic strip that can detect changes in the temperature of its contact. When the current flow through the contact of the breaker exceeds the rated current of 15A, the temperature of the contact increases and the bimetallic strip bends. This bends the upper and lower ends of the contact, separating the open and closed contact points, so the circuit will break and stop the current flowing.

In addition, the PR21-62F-15.0A-32851-1-V rated current 15A circuit breaker is equipped with a thermal element, which stores some of the heat generated by the current to help break the circuit. This ensures that the current is quickly interrupted when the circuit overloads.

Safety Precautions

It is important for users to know how to properly use a circuit breaker. Always make sure the breaker is suitable for the device or circuit you are using. If a circuit is tripping repeatedly, or an appliance shuts off permanently, it may indicate that the circuit is overloaded and needs to be re-configured. Moreover, the circuit breaker should not be used to protect against the hazards of electric shock or to control power to energized equipment.

If a circuit breaker fails to work properly, switch off the circuit breaker at the source, remove the fuse, and check the circuit for any signs of damage or burnt wiring. Repair will be required depending on the extent of the damage, but it is recommended to consult with a qualified electrician for guidance on how to fix the problem.

In summary, PR21-62F-15.0A-32851-1-V rated current 15A circuit breakers are designed to protect electrical circuits from damage caused by overload or short circuit. It is important to be aware of the safety precautions, and to ensure that the breaker is suitable for the device and circuit before it can be used.
