The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load.

The transformation of the power landscape involves more than just generation. The distribution of electricity is being changed as well, with technology designed to make electrical systems safer, more ...

Thermal-magnetic circuit breakers contain two different switching mechanisms, a bimetal switch and an electromagnet. The bimetal serves as a means of handling overcurrents. The bimetal typically sits ...

ABB has released the Switching Control Sentinel (SCS) device designed for high-voltage circuit breakers. Voltage and current transients generated during switching of high-voltage circuit breakers are ...

An extremely versatile range of rocker switch/thermal circuit breakers (S-type TO CBE to EN 60934 with trip free mechanism) offering the choice of single pole, double pole with single pole protection, ...

For utilities, proper protection against high voltage transient overvoltages and overloads is critical to ensure maximum life of their power transformers. Failure to do so can result in significant ...

Menlo Microsystems, Inc. (Menlo Micro), a developer of high-performance switches, has announced the successful completion of ...
