Circuit breakers are safety devices which protect both people and components from short circuits, overloads and other electrical problems. The LEBLXPK11-34417-150 is a single pole, double throw, thermally operated circuit breaker normally configured to provide over-current protection. The device is designed to provide over-current protection in applications requiring positive contact opening and closing.

Application field and Working Principle

The LEBLXPK11-34417-150 has a wide range of applications, most notably for use in residential and commercial wiring, as well as industrial applications such as motor starters, transformers, pumps and compressors. It is also used in some instances as a ground fault circuit interrupter (GFCI). The operating principle of the LEBLXPK11-34417-150 is straightforward. When the load current passes through the device, it produces a precise amount of heat which is measured by a thermal element. If the amount of heat exceeds a pre-determined threshold, the thermal element will activate and switch the circuit off, thus protecting all connected components and people.

The LEBLXPK11-34417-150 provides enhanced protection when used in conjunction with reverse-tracking temperature control systems. In this type of system, the temperature of the thermal element is compared to the maximum temperature required to operate the circuit, and if this maximum temperature is exceeded, the breaker disconnects the circuit. Reverse-tracking systems are particularly useful in applications where the load current can fluctuate considerably (such as in motor starters), and will help preserve the integrity of the system by monitoring and automatically shutting down when necessary.

The LEBLXPK11-34417-150 also provides excellent protection when used in applications with both single- and three-phase systems. Here, the breaker works to protect against overvoltage and 100% overload. It is important to note, however, that the breaker will only provide protection up to 18 amps in three-phase applications, and 45 amps in single-phase applications.

The LEBLXPK11-34417-150 is a reliable and efficient device for over-current protection, and integrated into a variety of applications it provides an extra layer of safety and protection. With its temperature-controlled trip system, it will ensure that no existing load will be damaged as the result of an overload or short circuit. The device is a great choice for a diverse range of applications, and its robust construction and design offers excellent reliability and performance.
