Circuit Breakers

Circuit breakers are designed to protect an electric circuit from damage or failure due to over current, short circuit, or other abnormal conditions. The IELHK1111-34694-1-V is a specific type of circuit breaker that is designed to be used in high voltage applications.

Application Field

The IELHK1111-34694-1-V can be used in various higher voltage applications, including power distribution systems. It can be used in medium voltage systems up to 13.8 kV with a maximum short circuit current of 40 kA. It is also suitable for ground fault protection in three-phase systems. Additionally, the IELHK1111-34694-1-V is suitable for motor protection, lighting and heating systems and with a wide voltage range, it can be used in industrial and commercial environments for all kinds of applications.

Working Principle

The IELHK1111-34694-1-V is designed to break any electrical circuit if it senses an abnormal current or voltage. It has two main elements, the trip mechanism and the connection. The trip mechanism consists of a spring and a trip coil. The trip coil is connected to a relay or a contactor, which actuates when the current or voltage passes a certain set point. When this happens, the trip coil is activated, causing the spring to break the electrical connection.

The connection consists of two opposing movable contacts that come together or close when the current passes through them. As the current increases, the contacts expand and become wider until they completely close the circuit. When the current or voltage passes a certain set point, the trip mechanism is activated and the contacts are pushed apart to break the connection.

The IELHK1111-34694-1-V is designed to protect an electric circuit from damage due to over current, short circuit, or other abnormal conditions. It is reliable and safe, and can be used in high voltage applications. The trip mechanism and the connection elements work together to ensure that the circuit is protected against any potential damage.
