Circuit Breakers

Circuit breakers, also called circuit protectors, are specialized electrical switchgear designed to protect electrical power systems from damage due to overload, short circuit, or ground fault. Circuit breakers are a component within a larger electrical system, commonly known as a power distribution system. They can also be built into smaller pieces of equipment, such as washing machines, for domestic use.

229M-3-1-62-8-6M-50-A Circuit Breaker

The 229M-3-1-62-8-6M-50-A circuit breaker is a type of circuit breaker designed to protect electrical circuits from overload currents and short circuits. It is a three-phase, four-pole circuit breaker with manual override, capable of breaking currents up to 62,000A in both open and short circuits. The 229M-3-1-62-8-6M-50-A is also equipped with an adjustable trip head for setting trip values. It features a continuous temperature operational range between -20 degrees Celsius and +85 degrees Celsius.

Application Field

The 229M-3-1-62-8-6M-50-A circuit breaker is primarily used to protect medium and large-scale distribution systems such as industrial units, shopping centers, hospitals, and tall buildings. It can also be used in residential buildings where it is used for power overload protection. This type of circuit breaker also has a wide range of applications in automatic control systems, power supplies, and electric traction systems.

Working Principle

The 229M-3-1-62-8-6M-50-A circuit breaker works by sensing the current and voltage in a circuit and breaking the circuit when either of them exceeds a certain limit. This limit is determined by a “trip unit,” which is a set of built-in sensors that measure the amount of electricity in the circuit and sends a signal to the circuit breaker when it reaches an unsafe level. Once the trip unit signals the breaker, the breaker instantly disconnects the current from the circuit, thus shutting down the power supply. To reset the circuit breaker, the breaker must be manually reset by using the override switch.

Advantages

The 229M-3-1-62-8-6M-50-A circuit breaker has several advantages, such as providing complete short circuit protection, providing overload protection, manual override for resetting the circuit breaker, and adjustable trip head for setting trip values. Furthermore, it has a broad operational temperature range and is capable of breaking currents of up to 62,000A in both open and short circuits.
