Product type
Air circuit breakers are electrical devices designed to protect electrical circuits from overloads and short circuits. They operate by using air as the medium for arc extinction when the circuit is interrupted. Typically made from high-quality insulating materials and metal components, these breakers are essential for ensuring the safety and reliability of electrical systems in various applications.
