1.1Product Functions and Features

The Circuit Breaker Panel With Reset Switch supplies low-voltage, protected dc power to –24 Vdc or –48 Vdc powered equipment installed in a central office, multimedia headend, remote site, or other restricted access location. The panel provides the following functions and features:

•Two side-by-side power buses, designated A and B, each with seven power outputs.

•Fourteen circuit breakers (seven per bus). Each bus has two 10 Amp circuit breakers and five 5 Amp circuit breakers.

•Maximum input rating of 45 Amps per bus. This corresponds to a maximum input rating of 90 Amps for the total panel.

•One Power On LED (green) and one Breaker Alarm LED (red) for each bus.

•One Reset switch for the total panel. The Reset switch allows the operator to reset the panel to a non-alarming state if a breaker has been turned off or tripped due to an overcurrent condition.

•Alarm contacts (screw-down barrier terminal strips) for remote reporting of an alarm condition. The alarm contacts can be used to open or close a loop connected to an external alarm system.

•Mounting brackets providing the ability to mount the panel in a 19-inch (482.6 mm) or 23- inch (584.2 mm) WECO or EIA equipment rack. The panel occupies one rack space (1.75 inches, 44.4 mm).

Note: The panel requires one open rack space above the chassis and one open rack space below the chassis for heat dissipation.

•Two-hole compression-lug style terminals for input power connections.

•Screw-down barrier terminal strips for output power connections.

•Two chassis ground studs.

•Easy to remove rear protective covers. These covers mount over the input and output power connections to prevent inadvertent contact.

Circuit Breaker Panel With Reset Switch specifications

An ADC Circuit Breaker Panel with Reset Switch is an essential component in modern electrical systems, designed to enhance safety and efficiency in power distribution. This panel serves as a protective mechanism, safeguarding electrical circuits from overloads and short circuits, while the reset switch provides a user-friendly means of restoring functionality without the need for complete disconnection.

One of the primary features of the ADC Circuit Breaker Panel is its advanced circuit protection technology. Utilizing either thermal or magnetic mechanisms, these breakers can detect abnormalities in current flow and automatically interrupt the circuit. Thermal breakers respond to excessive heat generated by an overload, while magnetic breakers react quickly to short circuits, ensuring minimal damage to both the electrical system and connected appliances.

Another important characteristic of this panel is its modular design. The customizable layout allows for the integration of various circuit breakers based on specific requirements, accommodating different circuit voltages and capacities. This adaptability makes the ADC Circuit Breaker Panel suitable for a wide range of applications, from residential homes to commercial buildings and industrial settings.

Energy efficiency is a key concern in modern electrical design, and the ADC panel plays a significant role in this aspect. With features like smart monitoring systems, users can keep track of power consumption, helping to identify inefficiencies and reduce energy waste. This promotes sustainable practices and can lead to significant cost savings over time.

Incorporating modern technologies, these panels often come equipped with digital displays and connectivity options. This enables real-time monitoring and alerts for any irregularities, enhancing overall system reliability. Some models even support remote access, allowing users to manage and monitor their electrical systems from anywhere, further increasing convenience and safety.

Moreover, safety is paramount in the design of ADC Circuit Breaker Panels. The inclusion of a reset switch means that instead of replacing blown fuses or constantly resetting breakers manually, users can simply press the switch to restore power. This feature not only saves time but also reduces the risk of accidental electrical mishaps.

In summary, the ADC Circuit Breaker Panel with Reset Switch blends advanced technology, adaptability, and enhanced safety features into a compact design. With its capacity for efficient energy management and user-friendly operation, it stands out as a crucial element in the evolution of electrical distribution and protection systems.
