Each of the power buses supports seven circuit breaker positions including two 10 Amp circuit breaker positions and five 5 Amp circuit breaker positions giving a total capacity per bus of 45 Amps.

When a circuit breaker trips, the input power bus is disconnected from the corresponding output circuit.

1.5Input Voltage

The dual bus circuit breaker panel can accommodate either –24 Vdc on both buses or –48 Vdc on both buses.

Warning: Use of one bus only on a dual bus panel will result in false alarms for the unused bus. Power is required on both buses on a dual bus panel for normal operation.

The voltage level is sensed by the circuit breaker panel circuitry. The input voltages used with the circuit breaker panel can fall within the following ranges:

•–24 Vdc nominal, within range of –21 Vdc to –30 Vdc

•–48 Vdc nominal, within range of –42 Vdc to –56 Vdc

1.6Input Connectors

Each power bus has two input connectors on the rear of the circuit breaker panel through which input power is provided. The two input power connectors are labeled “BATT” (battery) and “RTN” (return). Each input connector consists of a pair of 0.25-inch (0.635 cm) studs (with nuts) mounted on a plastic terminal block. Each pair of studs can accept different size 2-hole compression lugs used with a range of wire sizes up to #6 AWG copper wire. Two 2-hole lugs per bus for use with #6 AWG wire (four total) are provided with the circuit breaker panel. Additional lugs are available as accessory items. Maximum lug width is 0.62 inches (1.6 cm). In selecting the copper wire size to be used for power input, consider the allowable ampacity as defined by local practice and the National Electrical Code (refer to Appendix A).

1.7Output Voltage

The output voltage will be the same as the applied input voltage.

1.8Output Connectors

Each bus has two screw-down terminal strips with seven 8-32 screws each on the back of the panel. The upper terminal strip contains the BATT (power feed) connectors. The lower terminal strip contains the RTN (return) connectors. When a piece of equipment is connected to the circuit breaker panel, it is connected to one BATT connector and one RTN connector located vertically above and below one another.

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.
