When the voltage at an input of a switch, multiplexer, or signal-line circuit protector exceeds the voltage that powers those devices, you define the excessive input voltage as a fault. This ...

A flexible circuit is shown that limits current or removes power in response to a command from the user or other fault-indicating signal. It accommodates manual-reset (MR), over-temperature, and ...

DC microgrids have emerged as a vital component in modern power system architectures, particularly for integrating renewable energy sources and distributed generation. These systems offer improved ...

If the service is a solidly grounded wye of more than 150V to ground but not more than 1,000V phase to phase, each service disconnect of 1,000A or more must have ground-fault protection [230.95]. This ...
