We see from your search that you're looking for information on the term "Circuit breaker",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Power centre produces 1200W at -48V from
Transistor Devices, which we summarised at the time by saying "Three hot-plug 400W rectifiers convert 90-264V AC into DC suitable for battery charging and float".
A couple of weeks before,
we featured the news release Resettable switch protects automotive electronics from
Raychem Circuit Protection: "The PolySwitch bladed contact device features a 2.8mm form factor to facilitate easy, one-to-one replacement of mini-sized fuses and Type II bimetal circuit protection devices in 12V vehicle systems".
In January 2008, we covered the news from Micrel
concerning its MIC2341 and MIC2342
- take a look at Hot-swap controllers meet PCIe specs
which says: "Ideal for high-performance enterprise computing network system processor boards, DDR memory boards, embedded systems and gigabit Ethernet addon cards".
Take a look also at the news release from Aerco, Circuit breaker protects distribution systems,
as well as Farnell is first with connector lines from ITT Electronic Components,
and Thermal circuit breaker adds mounting options from Schurter.
