This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...

You may have experienced a short circuit on a 15A to 100A branch circuit that also tripped the main breaker in that same panelboard, resulting in widespread downtime. This short circuit may have ...

Per 2014 NEC Article 100, short circuit current rating (SCCR) is defined as: “The prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected ...

In solar PV systems, circuit breaker selection is something that is easily overlooked and time should be taken to select the correct solution. If the circuit breaker is not appropriate, it will cause ...

Explore key insights into miniature circuit breakers, including how they differ from fuses, what selection criteria to consider and their coordination with protective devices for optimal electrical ...

Industrial automation customers can improve their short-circuit protection with a new line of current-limiting, molded-case circuit breakers from Rockwell Automation. The line expands the ...
