UPL1111-755-13 Circuit Protection

Circuit breakers are devices designed to protect circuits and are used to limit excess current flowing through an electrical circuit. The UPL1111-755-13 is a particularly specialized type of circuit breaker, developed for use in AT&T\'s 5ESS switch automation platform. It is designed to quickly and reliably disconnect the power current once an overload is detected, thereby protecting the system from damage due to high currents. Having this specialized circuit breaker enables AT&T to optimize its overall switching performance.

The UPL1111-755-13 circuit breaker is a sophisticated and highly reliable device. It features a high efficiency and low resistance switching mechanism, which helps reduce the power lost during interruption. This ability to precisely measure, detect and control the flow of the current makes it especially suited for applications where precise control is necessary. It also has a much lower impedance than other similar circuit breakers, making it more capable of handling large currents without overheating. The UPL1111-755-13 is also designed to minimize the amount of arcing during interruption, providing an extra layer of protection against sparks.

The performance of the UPL1111-755-13 circuit breaker is further enhanced by its unique design. The device utilizes high breakdown voltages, thereby providing extra protection from voltage spikes and surges. It also employs a double inertia system, which enables it to quickly cut off the current in the event of an overload, even without a secondary protection circuit. In addition, the device is equipped with advanced electronic components, such as an ESD protection layer, which protect the circuit against Electrostatic Discharge damage.

The UPL1111-755-13 circuit breaker is able to perform its task thanks to its internal working principle. The device utilizes a thermal overload relay as its central element, which detect excess current and then open a mechanical contact to interrupt the circuit. The thermal overload relay also works in conjunction with a thermal-magnetic switch and a contactor switch, both of which act to determine when current overloads are detected and to activate the circuit breaker. The contacts of the device are usually silver-plated for better conductivity, and its overall design is meant to be highly durable and reliable.

The UPL1111-755-13 circuit breaker is highly useful in telecommunications, where reliable control of the current is a necessity. Its smart internal design enables the device to precisely monitor the current flow and rapidly cut off the power whenever an overload is detected. Coupled with its low resistance and high reliability performance, the UPL1111-755-13 provides the ideal solution for critical applications. It is also suitable for use in other types of industries, such as industrial automation, where precise control of current and reliable protection is needed.
