Generally used where for some reason it is desired to replace an IC with a connection to an external device (e.g., in-circuit emulators). Can also be used like a PCB transition header, especially on stripboard. (Fitting a standard-spacing header to stripboard is tricky, because you have to cut the tracks between two holes rather than on a hole.)
If a panelboard with a sufficient number of breaker positions is installed in the first place, the need for non-CTL breakers should be eliminated. In their 2019 catalog Eaton now specifies that their non-CTL breakers are "Suitable for use in plug-on neutral style loadcenters" [ 4 ] which negates the replacement only rule.
Air-break circuit breakers replaced oil-filled units for indoor applications, but are now themselves being replaced by vacuum circuit breakers (up to about 40.5 kV). Like the high-voltage circuit breakers described below, these are also operated by current-sensing protective relays operated through current transformers. The characteristics of ...

A switched-mode power supply operating at the current limit with the output short-circuited does not have increased power dissipation in the power transistor(s), so foldback current limiting is an application feature only rather than one that also prevents a load fault from also destroying the power supply. The safety benefit of reducing the ...

Power outages are categorized into three different phenomena, relating to the duration and effect of the outage: A transient fault is a loss of power typically caused by a fault on a power line, e.g. a short circuit or flashover. Power is automatically restored once the fault is cleared. A brownout is a drop in voltage in an electrical power ...
