We see from your search that you're looking for information on the term "Short Circuit",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release System protects against installation damage from
Eltra, which we summarised at the time by saying "Eltra's EL40 short circuit protection system avoids damage if an output channel is connected to the power supply".
A couple of weeks before,
we featured the news release Connectors avoid over-termination dangers from
Pepperl+Fuchs GB: "R2 segment protectors provide IP20 protection with DIN rail mounting, in 4, 6, 8, 10 and 12 spur configurations".
In December 2007, we covered the news from System Control Solutions
concerning its Delta VFD-EL
- take a look at Micro drive cuts costs on the panel
which says: "AC micro drive is designed to cover low power voltage/frequency applications using the latest 'contactor' style wiring format, allowing side by side panel installation".
Take a look also at the news release from Industrial Encoder Corporation, Encoders take on hazardous duties,
as well as IR sensors monitor racing tyre performance from Micro-Epsilon UK,
and Motor starters run up to 90kW from Moeller Electric.
