Bob and Btu Buddy were on a service call yesterday where the compressor motor was running overloaded due to internal load; the bearings were dragging or worn. Btu Buddy told Bob, “Motor overload ...

To prevent a motor from burning up, you must provide a means of protecting it from overcurrent (overload, short circuit, or ground fault). If you can remember not to confuse motor protection with ...

In troubleshooting situations involving a motor, more than half the battle is simply isolating the problem. So when problems arise, how can you tell if it is the drive, the motor, or the load? Here ...

While these units perform as combination controller/disconnect devices, they are also suitable as combination controller/overload protection components. Other applications include using the components ...

Article 430 of the NEC details motor branch-circuit requirements for short-circuit and ground-fault protection, as well as motor-overload protection.

These including amperage/voltage ratings, i2t (motor overload/thermal) protection, breaking capacity, and time-current speeds.

These components comprise motor starting contactors, motor-specific circuit breakers and motor-overload relays where, depending on the application, the motor overload functionality can be incorporated ...

Enhancing motor-drive apps with added safety, the ACPL-785J isolation amplifiers include both short-circuit and overload detection and allow direct measurement of motor phase currents in power ...

Overloading electrical circuits is easier than you may think, especially around the holidays. At best, overloading the circuit is inconvenient, but it can also be dangerous.

San Jose, Calif.—Avago Technologies announced a new series of competitively priced isolation amplifiers with short circuit and overload detection. Based on optical insulation technology and ...
