Eta Circuit Breakers

Intelligent electronic device - An Intelligent Electronic Device (IED) is a term used in the electric power industry to describe microprocessor-based controllers of power system equipment, such as circuit breakers, transformers, and capacitor banks. These IEDs receive data from sensors and power equipment, and can issue control commands, such as tripping circuit breakers if they sense voltage, current, or frequency anomalies, or raise/lower voltage levels in order to maintain the desired level.

Residual-current device - In electrical installations, residual current devices (RCD) "Ground Fault Circuit Interrupter"; along with residual current circuit breakers (RCCB) operate to disconnect a circuit whenever they detect that the flow of current is not balanced between the phase conductor and the neutral conductor which is commonly connected to earth. These devices can be tested to see if they are operational and/or they have been wired correctly.

Distribution board - A distribution board (known in the United States as a (circuit) breaker panel, panelboard, or load center or for old ones, fuse box) is a mounting enclosure for multiple electrical circuit breakers. These are generally placed in two rows.

Voltage spike - Voltage spikes are fast, short duration surges (overvoltages) in the electric potential in a given circuit. These are typically caused by lightning strikes, although power outages, tripped circuit breakers, short circuits, and power transitions in other large equipment on the same power line, and malfunctions caused by the power company can also cause them.
