A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal ...

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 ...

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), ...

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 ...

AutomationDirect announces the release of a new White Paper, “Group Motor Protection”, that explains how the usual way of preventing a small motor from drawing too much current is to install ...

The usual way of preventing a small motor from drawing too much current is to install overcurrent protection in the form of a circuit breaker or some other kind of limiter. But installations that ...

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 ...

The C440 and XT electronic overload relays provide motor protection. They feature both integral ground fault protection and communications capabilities, in a single, compact device. They directly ...

Rockwell Automation’s Branch Motor Controls and Protection Solutions offer a range of combinations and accessories for applications that require smart industrial control. Electric motor starters ...
