Circuit breakers are an important part of any electrical system. They are designed to protect wiring, systems, and equipment from damage as a result of voltage surges. The 1E125UM circuit breaker is a popular and reliable choice for many applications. In this article, we will discuss the application field and working principle of the 1E125UM Circuit Breaker.

Application Field
The 1E125UM Circuit Breaker is designed for outdoor systems in both residential and commercial settings. It is suitable for 10KA/6KA fuse, and features thermosetting insulated plastic in the core apparatus and cast aluminum alloy housing. This makes it suitable for use in environments with high temperatures and high humidity. As such, this circuit breaker is commonly used in generators, HVAC systems, and automated systems.

Working Principle
The 1E125UM Circuit Breaker is equipped with an over-current protection device. This device is designed to detect any improper current flow in the system, and open or close a circuit when the flow of current exceeds a safe limit. This helps to prevent overheating or short-circuiting within the system, and thus preserving the lifetime of equipment. In addition to over-current protection, the 1E125UM also provides thermal protection. This helps to protect the system from damage caused by excessive heat buildup.

When the 1E125UM Circuit Breaker detects an over-current situation, it will open the circuit through a solenoid coil. This disconnects the circuit, preventing further damage and injury associated with the over-current situation. The 1E125UM also features an automatic reset prevention mechanism. This mechanism ensures that the circuit breaker will only reset when the current has returned to its normal level, rather than resetting automatically.

The 1E125UM Circuit Breaker is also equipped with a manual reset device. This allows for manual resetting of the circuit when over-current or thermal protection is triggered, as well as for testing and inspection. This manual reset device is a convenient and reliable way to reset the breaker when needed.

In addition to its over-current, thermal, and manual reset protection features, the 1E125UM Circuit Breaker also provides ground fault protection. In the event of a ground fault, the 1E125UM will detect the short circuit and open the circuit, thus preventing further damage. This is an important feature for ensuring the safety of personnel and equipment in the event of a ground fault.

The 1E125UM Circuit Breaker is an excellent choice for many residential and commercial applications. It is designed to protect the system from over-current and thermal overloads, while providing ground fault and manual reset protection when needed. The 1E125UM is a reliable and cost-effective way to keep your system safe, and provide the controlled power it needs.
