Circuit breakers are among the most important components in electrical safety and power management systems. They are used to interrupt a circuit in the event of a fault or overload, protecting both components and personnel. APGH66-35349-4 is a type of circuit breaker manufactured by APGH, used across a range of applications where circuit protection is required. This article provides an overview of the APGH66-35349-4 application field and its working principle.

The APGH66-35349-4 is suitable for low and medium voltage applications, ranging from 1kV to 8kV. This makes it well equipped to provide circuit protection in power circuits and all related ancillary circuits. In addition, it is frequently used in distribution, communication, protection, and control circuits, making it well suited for use in industrial, commercial, and residential settings. The APGH66-35349-4 is a type D breaker, which means that it is protected against short-circuit, over-current, and overload, making it a valuable device for protecting both life and property.

The APGH66-35349-4 is designed for both manual and automatic operation. In manual mode, it allows for an operator to activate or deactivate the circuit breaker in the event of a fault or overload. This allows operators to quickly and safely disconnect the circuit without the worry of overcurrent or overloads. In automatic mode, the APGH66-35349-4 is equipped with a thermal-magnetic trip system, which consists of a thermal element and a magnetic element. The thermal element monitors current within the circuit, and if it exceeds a set threshold, the circuit breaker is triggered and the current is interrupted. The magnetic element detects an increase in magnetic field strength and triggers the circuit breaker if the current exceeds a set threshold. This provides an additional layer of protection, ensuring that the circuit breaker is triggered quickly and seamlessly, without overloading or damaging any components.

In addition to the manual and automatic operation, the APGH66-35349-4 provides several other important features. It is equipped with an adjustable trip current, allowing operators to set the threshold at which the circuit breaker will be triggered. This provides flexibility and ensures that it can be used in a variety of settings. It also features a quick return principle, which allows the circuit breaker to quickly resume operation after tripping. This helps to reduce downtime and allows for efficient and safe circuit management.

The APGH66-35349-4 is an incredibly important and reliable piece of safety equipment. Its manual and automatic operations, adjustable trip current, and quick return principle make it an ideal choice for protecting circuits and personnel from faults, over-current, and overloads. It is designed for low and medium voltage applications, making it suitable for use in a wide range of industrial, commercial, and residential settings.
