Circuit Breakers: 992225 Application Field and Working Principle

Introduction

A circuit breaker is a device that disconnects an electrical circuit when the current surpasses a safety threshold to prevent damage and personal injury from electrical overloads. The 992225 model of circuit breaker is a three-phase circuit breaker that serves as a protective device from electrical surges. This type of circuit breaker is often used in residential, commercial and industrial buildings and is suitable for a wide variety of applications.

Application Field

The 992225 circuit breaker is suitable for most types of circuits, including single-phase, three-phase and four-wire configurations. It is commonly used in residential dwellings, apartment complexes, commercial buildings and factories, as it is designed for a wide range of working conditions. The circuit breaker is rated with a voltage level up to 600-volts and 800 amperes, rating (A) at 40 ̊C.The 992225 circuit breaker can be used for various appliances such as, TVs, refrigerators, air conditioners, furnaces, water heaters, dryers, stoves, dishwashers, washing machines, microwaves, and other electronic devices. Additionally, it is suitable for welding machines, motors, and other machines that use three-phase connections.

Working Principle

The 992225 circuit breaker is equipped with a bimetallic strip, which is responsible for monitoring the flow of current and short-circuiting the circuit when it reaches a dangerous level. The bimetallic strip is composed of two metal strips that are bonded together, typically made of metals with different thermal expansion coefficients such as brass and iron, or copper and aluminum. When current passes through the strip, the two metals expand at different rates, causing the strip to bend and closing the contacts of the circuit breaker.When the current reaches a level that is too high or if there is a short-circuit, the bimetallic strip bends and closes the contacts. This causes the electric current to be cut off and the circuit breaker to reset. When the bimetallic strip returns to its normal state, the electric current will resume passing through the circuit.

Conclusion

The 992225 model of circuit breaker is a reliable and secure device for protecting electric circuits from overheating, electrical surges, and short-circuits. It is suitable for a wide variety of residential, commercial, and industrial applications and is equipped with a bimetallic strip which cuts off the electricity to the circuit when it reaches a dangerous level. By utilizing the 992225 circuit breaker, individuals can ensure the safety of their electrical circuits and prevent any potential damages or personal injury.
