A circuit breaker is designed to protect an electrical circuit from damage caused by overload or short circuit. The PP21-62-8.00A-OB-V is one type of circuit breaker and is widely used in commercial, industrial and residential applications. This article will discuss the application field and working principle of the PP21-62-8.00A-OB-V.

The PP21-62-8.00A-OB-V circuit breaker is a thermal-magnetic breaker designed for moderate and heavy current load applications. The thermal-magnetic technology combines thermal and magnetic elements that work together to detect both overloads and short circuits. When either of these conditions occurs, the breaker opens, disconnecting the circuit and preventing further damage to the system. The PP21-62-8.00A-OB-V is especially well-suited for use in commercial, industrial and residential buildings where the breaker must be able to handle frequent, high-energy switching cycles.

In terms of application field, the PP21-62-8.00A-OB-V can be used in a variety of commercial and industrial settings, including but not limited to: air conditioning and ventilation applications, control panels, control and protection of electrical circuits, and power distribution units. In addition to this, it can also be used in buildings where the breaker needs to switch on and off quickly and frequently, such as fast food restaurants, supermarkets or manufacturing plants. From a residential standpoint, the PP21-62-8.00A-OB-V can be used in air conditioning and ventilation systems, lighting, emergency lighting and power distribution systems.

The working principle of the PP21-62-8.00A-OB-V is as follows: The breaker’s thermal-magnetic technology combines both thermal and magnetic elements to detect and respond to overloads and short circuits. The thermal element measures the circuit’s current and reacts when the current exceeds the breaker’s rated current. This causes the element to heat up, which in turn causes a bimetal strip to bend and the breaker to trip. The magnetic element is also sensitive to current but reacts in a different way. When a short circuit occurs, the magnetic element produces a magnetic field that causes a plunger to trip, which in turn causes the breaker to trip.

In conclusion, the PP21-62-8.00A-OB-V is a thermal-magnetic breaker designed to protect electrical circuits from overload and short circuit damage. Due to its thermal-magnetic technology, it provides fast response times and is well-suited for frequent and high-energy switching cycles. It is suitable for applications in residential, commercial and industrial settings.
