1.12 Breaker Alarm Indicators

For each bus, the circuit breaker panel has one visual Breaker Alarm indicator (red LED) mounted on the front of the panel. The breaker alarm indicator lights if any circuit breaker on the corresponding bus trips off. Loss of power to either bus will cause the circuit breaker alarm indicator for the corresponding bus to be off.

1.13 Alarm Operation

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.

Each bus contains circuitry that operates a set of Form C alarm relay contacts when any circuit breaker on the bus trips off or when input power to the bus is lost. The alarm contacts may be used to open or close a loop connected to an external alarm system.

Alarm connections are provided though a screw-down barrier terminal strip located on the rear side of the panel. During normal operation, the normally open (NO) contacts remain open and the normally closed (NC) contacts remain closed. When a circuit breaker trips or power is lost, the NO contacts close creating a connection from NO to common (C), and the NC contacts open creating an open circuit between the NC and C contacts. When the Reset button is tripped, these contacts return to a normal operational state.

The maximum current rating for each set of alarm relay contacts is 1.0 Amp.

1.14 Alarm Connections

The panel has a screw-down barrier terminal strip for the alarm relay contact connections. The screw-down terminal strip consists of two single row terminal blocks, each with three 3-48 screw terminals. The screw terminals are mounted on 0.250 inch (6.350 mm) centers with a maximum distance between barriers (maximum connecting terminal width) of 0.200 inch (5.080 mm). The three terminals in each row are labeled NO, C, and NC. The terminals will accept #16 to #30 AWG copper wire with insulation stripped back.

1.15 Reset Switch

The Reset switch, when tripped, stops the reporting of any current alarms due to circuit breakers being in the off position. In this state, only new alarms are reported.

1.16 Circuit Breaker Designation Card and Holder

A circuit breaker designation card as shown in Figure 4 and a card holder are provided with the circuit breaker panel. The card holder is intended to be attached either to one of the panel mounting brackets, to a part of the rack in which the panel is installed, at a location close to the panel, or to the underside of the panel, as desired.

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.
