Thanks to ongoing innovations in technology, electrical engineers' approach to motor protection has changed over the years. The traditional strategy to large AC motor protection (e.g., over 500 hp), ...

Motors differ from other types of loads in one important way: The motor needs much more current to start than to run. This temporary, but significant, inrush current is what complicates motor circuit ...

Bob is a service technician who is well trained and nationally certified. However, he sometimes suffers from the same confusion that all technicians occasionally do - the facts that he gathers may or ...

Group motor protection as described in NFPA 70, the U. S. National Electrical Code (NEC) Article 430.53 lets two or more motors be protected by the same overcurrent device as long as the installation ...

Electric drives require effective protection against overloads and short circuits. Both phenomena cause motor disruption and create a risk of damage to the motor. This could lead to a potentially ...

NORD’s motor portfolio adheres to global efficiency standards, supports a wide range of environmental conditions and offers ...

When it comes to downtime, motors are a disproportionally large contributor compared to other causes, simply because motors are used in so many processes, from pumping to material management. So, a ...

The 320 to 327 series motor pro- tection relays from NewElec provide protection for totally enclosed fan-cooled, S1-rated, low-voltage and medium-voltage metric motors with the most favourable core ...
