Circuit Breakers

IELHK111-30655-1 application field and working principle

Circuit breakers are important components in electrical systems. they are responsible for the safe operation of electrical equipment, preventing potential electrical fires, protecting equipment and people from electrical shock. The IELHK111-30655-1 is an example of a circuit breaker. This article will discuss both the application of the IELHK111-30655-1 and its working principle.The purpose of the IELHK111-30655-1 is to prevent sudden increases in circuit current that could potentially cause damage to the electrical system or the connected components. It is designed to protect electrical systems from short circuit and/or overloads and to preserve system operation and safety. The IELHK111-30655-1 is commonly used in residential, industrial, and commercial settings.The IELHK111-30655-1 circuit breaker is generally mounted in the panelboard. It consists of several key components, such as a bimetallic strip, trip lever, trip coil, arc chute, and adjustable shunt trips. When an overload current or short circuit current is detected, the bimetallic strip bends and causes the trip lever to open the contacts between the line and load. The arc chutes allow the arc to be contained within the breaker, preventing the arc from creating a potential fire hazard. The adjustable shunt trips can be set to monitor the current at different levels and trip the breaker as needed.The working principle of the IELHK111-30655-1 circuit breaker is based on the fact that high heat is generated by the large currents caused by an overload or short circuit. This heat affects the bimetallic strip, which has different thermal coefficients of expansion for each metal. As the strip is heated, it bends and triggers the trip lever mechanism that opens the contacts between the line and load. The adjustable shunt trips can be set to trip the breaker at a predetermined current level in order to prevent damage to the system from an overload or short circuit. This IELHK111-30655-1 circuit breaker is also equipped with a manual reset switch. This switch allows the circuit to be reset after it has tripped, if the current is no longer present. The switch also includes a safety feature that prevents the circuit from being reset if an overload is still present. The IELHK111-30655-1 circuit breaker also has a ground fault indicator. This indicator is used to detect ground fault current and trip the breaker if necessary. The ground fault indicator can be adjusted to detect current at different levels, allowing the user to set the protection level of the system. In conclusion, the IELHK111-30655-1 circuit breaker is an important safety device. It is designed to protect electrical systems from overload and short circuit currents. It operates on the principle of heat generated by these high currents which cause the bimetallic strip to bend, triggering the opening of contacts between the line and load. The manual reset switch, adjustable shunt trips, and ground fault indicator all add an extra layer of protection to the system.
