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.

NOJA Power's VISI-SWITCH OLB15-16-800 Load Break Switch will be commercially available in early 2017. This switch enables three-phase, medium-voltage distribution network manual isolation. It is a ...

The newly cloud-connected Leviton Load Center features intelligent circuit breakers that you can control or monitor from your phone. Originally hailing from Troy, Ohio, Ry Crist is a writer, a ...

Reviewing a typical protective device trip curve (click here to see Fig. 2), it can be divided into three regions. First is the “instantaneous region,” which is the region intended to interrupt ...

NOJA Power has introduced its VISI-SWITCH LBS15-16-800 for three-phase electricity distribution grid feeder manual isolation. The load break switch overcomes the drawbacks of sulphur hexafluoride (SF6 ...

Leviton has announced a new version of its Load Center breaker box for homes, and it’s adding an integrated Wi-Fi or Ethernet hub that will let you manage your home electrical setup directly from your ...

In the electrical profession, questions still arise about what type of circuit breaker to use with surge protectors. Don't make this task more difficult than it has to be. Choosing the right device is ...

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 ...

Churning with voltage and resembling an explosion at the wire factory, the breaker panel exudes mystique. But it's just a big switch, filled with other smaller ­switches, which lead to the switches ...
