This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...

Advancements in power TVS diodes have made them an effective alternative to metal oxide varistors (MOVs) in protecting AC and DC power supplies from power line surges and indirect lightning strikes.

TO BE READ BY ALL ELECTROSCHEMATICS ENTHUSIASTS! Much needs to be said about this oft neglected subject. We would never even think of connecting the utility mains to our house without proper circuit ...

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 ...

Fuses protect against overcurrent events by melting their elements and opening the circuit. Fuses must be applied at or below their specified voltage rating, which differs between ac and dc current.

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.
