Circuit breakers are used in a variety of ways. They are mounted in panelboards to protect branch circuit wiring, and they are built into equipment to protect it. With this range of applications, it's ...

The global demand for green energy sources is driving strong market growth for solar power systems. Although a great deal of development work is still focused on making PV (photovoltaic) energy ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

Now that autos are moving toward high-powered battery voltage, the industry is turning new attention toward making sure the flow can stop on a dime when needed. Power management company Eaton Corp.

Versatile, scalable gate drivers rated for 1200 V and 1700 V applications SAN JOSE, Calif.--(BUSINESS WIRE)--Power Integrations (NASDAQ: POWI), the leader in gate-driver technology for medium- and ...

A German research team has developed a semiconductor-based protection concept tailored to renewable energy systems that forces a permanent short circuit in less than 1 millisecond in the event of a ...

If a motor isn't adequately protected, a short circuit will likely result in premature replacement. Then there's the problem of nuisance tripping upon initial start-up because the magnetic setting of ...

It features a standard 2.5-sq-mm screw-clamping system (22 to 12 awg), and accepts a standard 5 20-mm fuse. Various LED options provide blown fuse indication across a voltage range of 10 to 250 V. The ...
