ACB Breaker, or Air Circuit Breaker, is a crucial component in electrical systems, responsible for controlling the flow of current and protecting the system from overloads and faults. It plays a pivotal role in ensuring the safety, reliability, and efficiency of various power systems, including industrial, commercial, and residential applications.

The working principle of ACB Breaker is based on thermal-magnetic trip mechanisms or electromagnetic attraction and release principles. When the current in the circuit exceeds the rated value, the trip mechanism is activated, either through thermal expansion or electromagnetic force, causing the breaker to trip and interrupt the circuit promptly. This prevents equipment damage due to overloads and ensures the continued operation of the power system.

ACB Breakers are renowned for their modular design, which allows for easy maintenance and replacement. The drawer-type structure enables operators to access and service the breaker without disrupting the entire electrical system. This feature significantly reduces maintenance costs and enhances the availability of the power system. Additionally, ACB Breakers offer flexible configurations, enabling users to select drawers with different rated currents based on their specific requirements. The reliability and durability of ACB Breakers are attributes that make them highly sought-after in various industries. They are designed to withstand high currents and extreme operating conditions, ensuring stable performance even under challenging circumstances. The breakers also feature multiple protective functions, such as overload protection, short-circuit protection, and earth fault protection, providing a comprehensive safeguard for the electrical system.
