A circuit breaker is a device designed to protect electrical circuits against fault currents. The APGH666-3REC3-9739-30 model uses a combination of electromechanical and electronic components to detect, intercept, and operate in the event of an overload or short circuit. These types of breakers are typically mounted on a panelboard or circuit breaker box to provide an extra layer of electrical protection to the connected circuits. When an overload is detected, the breaker trips, or opens, and de-energizes the circuit, thereby preventing any further damage from taking place due to the overload.

The APGH666-3REC3-9739-30 offers more control and safety than traditional circuit breakers. It features a patented, three-phase recloser-type design, which utilizes a vacuum circuit breaker to provide reliable interruption performance. Furthermore, the breaker utilizes a sensing element in the form of an electromechanical switch. This switch senses small changes in current or voltage in the connected circuit. If an overload or other fault is detected, the switch operates the breaker and opens the circuit. This type of breaker is commonly used in both residential and commercial settings, mainly in heavy-duty industrial applications.

The APGH666-3REC3-9739-30 also features a unique semi-automatic feature that helps reduce maintenance costs and unnecessary operation of the breaker. The breaker is designed to automatically reset itself after an overload is detected and removed from the circuit. This ensures that the breaker will not continuously trip and potentially disrupt the power supply. This semi-automatic feature also helps to reduce the wear and tear on the user’s switchgear as well as its components.

In addition to protection from fault currents, the APGH666-3REC3-9739-30 also offers protection from accidental short-circuiting and other transient faults. Detecting and intercepting these faults requires the breaker to have a certain level of sensitivity and precision. To ensure this, this model is equipped with an algorithm that measures the rate of rise of current in the connected circuit. If the rate is too high, indicating a fault current, the breaker will quickly open the circuit and protect the power line.

The APGH666-3REC3-9739-30 provides an increased level of safety and protection compared to traditional circuit breakers. It is designed to provide reliable performance and accurate protection in industrial, residential, and commercial applications. Furthermore, its semi-automatic feature helps to reduce the wear and tear on the user’s switchgear and its components, as well as eliminating the need for constant manual resetting. With its advanced design and features, the APGH666-3REC3-9739-30 is an ideal choice for providing protection from fault currents, as well as accidental short-circuiting and other transient faults.
