IULHK12-34774-1 Application Field and Working Principle of Circuit Breakers

Circuit breakers are electrical devices used to protect against overload, short circuit, and ground fault. Circuit breakers can be used in various applications such as automotive, residential, industrial, and commercial. This article focuses on IULHK12-34774-1 and its application fields and working principle.The IULHK12-34774-1 circuit breaker is a low voltage device which is ideal for installation in new and existing systems in industrial, commercial, and residential applications. This breakers are designed to provide circuit protection for short circuit, ground fault, overload protection, and reverse power protection. It also features adjustable overload and short circuit tripping settings.This type of circuit breaker is of a compact construction and is available in several sizes. This makes them ideal for operating under harsh environmental conditions. The breaker also incorporates an arc extinguishing chamber and internal pressure compensation device which improves its safety performance.The IULHK12-34774-1 circuit breaker operates in three stages. In the first stage, when there is a normal load on the system, the breaker develops a preset opening pressure. When the load increases beyond the preset pressure, the breaker will switch to the second stage, where it will limit the current to the load. In the third stage, the breaker will open if the current exceeds the preset limits.When an external short circuit or overload occurs, a different mechanism is triggered. An over-current detector detects the increased current and sends an electrical signal to the trip coil which actuates the trip lever. The trip lever will eject the contacts out of the contact holder, thus breaking the circuit. The contacts will stay open until the current falls below the preset limit. Then the contacts will close again when the current has stabilized.The IULHK12-34774-1 circuit breaker is robust and reliable, and is highly suitable for industrial and commercial applications. Its adjustable overload and short circuit tripping settings make it suitable for various applications under various load conditions. Furthermore, its internal pressure compensation device makes it safe to operate. In addition, its arc extinguishing chamber ensures that any sparks generated by arc shorting are quickly suppressed. In short, the IULHK12-34774-1 is an excellent choice for any circuit protection requirement.
