Circuit breakers are one of the most important components in any electrical system. The PR21-42-7.50A-XX is a compact circuit breaker, designed to protect electronic components from the potentially detrimental effects of over-current or short-circuit events. It is ideal for applications such as control panels, motor control centers, vehicle applications, industrial automation systems and various other electronic devices.

The PR21-42-7.50A-XX performs its primary function of isolating electrical circuits by interrupting current flow in the event of an overload or short circuit. It consists of a bimetal element which is contained within a molded plastic case. The bimetal element is connected to the electrical contacts of the breaker, and is heated when a current passes through it. When the current reaches a level which exceeds the capacity of the circuit, the bimetal element will expand, causing the switch contacts to open, and thus separate the two halves of the circuit.

The PR21-42-7.50A-XX has a number of features which make it a great choice for many applications. To begin with, it has a low operating temperature, enabling it to provide quick and reliable protection even in the case of excessive current. The switch also has a dual-position breaking capacity, and a small moving contact that indicates when the breaker has been tripped. This can be useful when troubleshooting, as it will help to identify the specific source of an issue. Furthermore, the entire unit has a compact size, allowing it to fit in even the smallest spaces. The PR21-42-7.50A-XX also has an integral circuit status indicator which shows the current state of the circuit.

The PR21-42-7.50A-XX circuit breaker is also highly reliable. Its contact mechanisms are designed to provide long-term, reliable operation. The contacts are made from high-grade brass, which provides superior corrosion resistance and high electrical performance. Additionally, the breaker is protected by a heavy-duty spring-loaded device, which ensures the safe operation even when the unit experiences mechanical shock or vibration.

In summary, the PR21-42-7.50A-XX circuit breaker is an ideal solution for many applications, thanks to its compact design, low operating temperature, dual-position breaking capacity, safety features, and excellent reliability. It is especially useful in motor control centers, industrial devices, and control panels, where it can provide fast, accurate, and safe protection against over-current or short-circuit events.
