Circuit breakers are arguably the most important safety feature in electronics. They are designed to protect circuits from dangerous overloads, short circuits, and other potentially damaging conditions by momentarily interrupting the flow of electrical current. The PP21-2-15.0A-OB-V is one such circuit breaker, and its application field and working principles will be discussed in detail in this article.

The PP21-2-15.0A-OB-V is most suitable for install applications such as branch and interlock/feeder panel mount circuits. This type of circuit breaker is specifically designed for two-pole circuits and is capable of delivering up to 15.0A. It is a manually operated circuit breaker, with an integrated overcurrent protection and manual reset. The PP21-2-15.0A-OB-V is UL 489 listed, making it suitable for use in a variety of industrial applications.

As far as working principles are concerned, the PP21-2-15.0A-OB-V circuit breaker is designed to detect overload and short circuit conditions. If a current overload is detected, the internal contacts will open the circuit to interrupt the flow of current and prevent the circuit from being damaged. This is typically done by the use of a thermal-magnetic tripping system. This system uses a thermal element which is heated due to the increased flow of current. If the heat exceeds a particular threshold, the thermal element will expand and open the circuit. In addition to this, the magnetic component of the system also reacts to excess current, causing it to magnetize and draw the contactor together, thus opening the circuit.

The PP21-2-15.0A-OB-V breaker is also outfitted with an inrush current limiter, which helps to reduce the inrush current of the circuit when it is first powered on. This helps to reduce the load on the circuit and minimize the risk of damage. Additionally, the PP21-2-15.0A-OB-V breaker is equipped with a manual reset feature, which allows the user to quickly restore the circuit to its normal operating condition once the overload has been cleared.

These features, along with its ability to deliver up to 15.0A, make the PP21-2-15.0A-OB-V circuit breaker an ideal choice for a wide range of applications. From branch and interlock/feeder panel mount circuits to industrial applications requiring UL 489 listing, this circuit breaker has everything you need to ensure your electrical systems are safe and reliable. Invest in a PP21-2-15.0A-OB-V circuit breaker today and enjoy the benefits of quality circuit protection for years to come.
