Circuit breakers are devices used to protect the components and wires that make up a circuit or power grid. They are designed to interrupt a current or signal flow in the event of an overload or short circuit, preventing damage to the system. The LELH11-33908-20-V circuit breaker is a high-powered, low-temperature device typically used in the protection of large industrial machines and motors.The LELH11-33908-20-V is a two-pole, thermally-sensitive circuit breaker with a voltage rating of 690V AC. Its design is based on the traditional thermal magnetic principle, with a vacuum solution to quickly interrupt the current and ensure a safe operation. Its rated load current is 20A, making it suitable for protection of large equipment that must withstand higher currents.The LELH11-33908-20-V has a tripping time of 5 milliseconds, making it suited for circuits that require fast response times. This feature is especially important for industrial machines, which often rely on precise timing to carry out their processes. Furthermore, the time-delay function of the circuit breaker allows the user to choose between short-circuit and overload protection. This can be useful for large machines whose loads may fluctuate between maximum and minimum values.The LELH11-33908-20-V also features an adjustable trip setting, allowing the user to fine-tune the current limit of the circuit breaker to correspond with the anticipated load. This increases the level of accuracy and reliability of the protection system. In addition, this circuit breaker is equipped with a voltage rating limiter, which restricts the maximum voltage that can flow through the device. This prevents any unnecessary damage caused by over-voltage.The working principle of the LELH11-33908-20-V circuit breaker is based on the traditional thermal magnetic principle. When a fault, such as an overload or short circuit, occurs, the current flow exceeds the rated current of the breaker. This causes the temperature of the breaker to rise above the set threshold. This triggers a sensitivity mechanism which releases a plunger, separating the contacts and interrupting the current flow.The application field of the LELH11-33908-20-V circuit breaker is primarily industrial. It is used in the protection of harsh environments, including heavy-duty motors, filament melts, pumps, fixed or variable-speed drives, frequency converters, and other high-voltage and high-amperage applications. It can also be used in secondary distribution systems as protective devices for applications such as office buildings, shopping centers, and other indoor environments.In summary, the LELH11-33908-20-V circuit breaker is designed for protection of large industrial machinery and motors. Its two-pole, thermally-sensitive design is based on the traditional thermal magnetic principle, with a vacuum solution to enable quick interruption of current. It has a time-delay feature that allows for short-circuit and overload protection, and its adjustable trip setting increases the accuracy and reliability of the system. The main application field of this circuit breaker is industrial, but it can also be used in secondary distribution systems for indoor environments.
