Circuit breakers are among the most important safety components of every electrical system. They are designed to open a circuit and prevent it from being overloaded with too much current. The PP21-1-.500A-OC-V is a type of circuit breaker that has many applications and a few unique features. In this article, we will discuss the application field and working principle of the PP21-1-.500A-OC-V.

The PP21-1-.500A-OC-V is a type of low-voltage circuit breaker designed specifically for residential and commercial applications. It is compact and easy to install, making it ideal for small spaces. The circuit breaker also meets UL 489 requirements for safety and reliability. It also has an adjustable contact over-travel limiter, which helps to reduce nuisance tripping caused by power surges and other factors.

As its name implies, the PP21-1-.500A-OC-V is designed for low-voltage systems. It can be used in applications ranging from 250 to 500 volts AC. This type of circuit breaker is especially popular in applications such as air conditioning, lighting, power tools, and other electric motors. The circuit breaker can handle currents up to 50A and can be configured with a separate overcurrent device.

The PP21-1-.500A-OC-V uses a thermal-magnetic tripping system to protect the circuit from the overloads. This system uses both electromagnetic and thermal properties to detect and trip the circuit when the current becomes too high. When the current reaches a predetermined level, the electromagnetic force will open the circuit breaker by moving a set of contact bridges. This will interrupt the flow of electricity and prevent any damage to the circuit.

In addition to its tripping system, the PP21-1-.500A-OC-V also has a few clever features designed to reduce nuisance tripping. The adjustable contact over-travel limiter helps reduce nuisance tripping caused by surges and other external factors. The circuit breaker also has a Self-Latching Trip System (SLT) that ensures that when the circuit breaker trips it stays open. This prevents the circuit from being unintentionally reset, which can cause further damage to the system.

The PP21-1-.500A-OC-V is a powerful and reliable circuit breaker that is ideal for residential and commercial applications. It has a thermal-magnetic tripping system, an adjustable contact over-travel limiter, and a self-latching trip system that prevent nuisance tripping. All of these features make it a great choice for any low-voltage system from 250 volts AC to 500 volts AC.
