IELHK111-1-62F-45.0-ABE-01-V

Circuit Breakers are electrical protection devices used in various applications such as residential, commercial, and industrial settings to protect electrical systems from overloads and short circuits. The IELHK111-1-62F-45.0-ABE-01-V is an example of a circuit breaker, specifically designed for low voltage applications. This article will discuss the application field and working principle of this circuit breaker.

Application Field

The IELHK111-1-62F-45.0-ABE-01-V circuit breaker is widely used in commercial and industrial buildings, where it provides a reliable protection against overloads and short circuits. It\'s able to detect any current fluctuations in a connection and automatically disconnect it when a certain threshold is exceeded. That makes it ideal for safeguarding electrical systems in industrial and commercial applications, such as factories, offices and warehouses.

The IELHK111-1-62F-45.0-ABE-01-V is also approved for residential usage. It is UL-approved and designed for maximum protection in homes, including safety of family members and expensive home appliances, such as air conditioners and washing machines.

Working Principle

The IELHK111-1-62F-45.0-ABE-01-V circuit breaker works on the principle of thermal-magnetic protection. It consists of a pair of thermal-magnetic sensors housed in a single unit. When the current passing through the connections exceeds the set threshold, the internal sensors detect the overload and interpret it as a short circuit event. The circuit breaker then tripped and disconnects the connection.

The thermal-magnetic protection system works in two stages. At the first stage, the thermal sensor is activated in case of sustained overload and causes the breaker to trip. The thermal sensor has a faster response time than the typical magnetic sensors, offering more reliable protection against temporary overloads. At the second stage, the magnetic sensor is triggered and it takes care of any further short circuits beyond the thermal sensor’s response time.

The IELHK111-1-62F-45.0-ABE-01-V has adjustable trip settings that allow users to customize the protection level of the circuit breaker. To increase the protection level, the trip setting can be adjusted to trip sooner when current fluctuations occur. This ensures more reliable protection against overloads and short circuits.

Overall, the IELHK111-1-62F-45.0-ABE-01-V is a versatile circuit breaker that offers reliable and cost-effective protection for various applications. It’s UL-certified, has adjustable trip settings and works on the reliable thermal-magnetic protection principle.
