CR11-52-3.00A-34853-3-V

Circuit breakers are designed to protect electrical circuits from damage caused by excess current flow. A common circuit breaker design is the CR11-52-3.00A-34853-3-V, which is used in a wide range of applications due to its robust design and wide range of ratings. This article will explore the application fields of this circuit breaker as well as the working principle behind it.

Application Fields

The CR11-52-3.00A-34853-3-V is used in a variety of industries, from medical and military to automotive and data centers. Its widespread use is due mainly to its ability to handle extremely large current flows over a long period of time without failure. It can provide reliable short circuit protection in applications involving motors, electric arc welding, and electrical installations. It is also well suited to protect electric wires and busbars, particularly in areas with high ambient temperatures such as oil refineries, electric substations, and industrial power plants.

The circuit breaker has also been used in consumer electronics such as computers, cell phones, and other small electronic devices. It is especially useful in portable devices due to its compact design and reliable operation even when exposed to vibration. In addition, it can provide protection against surges and spikes that can damage sensitive electronic components.

Working Principle

The working principle behind the CR11-52-3.00A-34853-3-V is based on a simple principle. When current flows through the circuit breaker, the bimetallic strip inside it contracts or expands, depending on the current intensity. When the current reaches the threshold set by the circuit breaker, the strip moves and opens the contacts, thus interrupting the flow of current. This simple, yet effective, mechanism prevents damage to the circuit caused by over current or short circuit.

The circuit breaker can also be used in systems with motor protection, where it interrupts the circuit during a motor overload. This protects the motor and other components from damage due to excessive current or short circuiting.

Conclusion

The CR11-52-3.00A-34853-3-V circuit breaker is a versatile device that is commonly used in a wide range of applications. It offers reliable protection against overloads and shorts, and is particularly useful in systems with large motors. Its working principle is based on a bimetallic strip, which contracts or expands based on current intensity, thus interrupting the flow of current when the circuit breaker’s threshold is reached.
