Motors and their associated equipment must be protected against both overload and overcurrent (short circuit or ground fault). This function is usually split, with ...

In Part 1, we saw why we must separate overload protection from fault and short circuit protection for motor circuits. But correctly sizing these different devices can be confusing. And if you follow ...

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 ...

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 ...

In troubleshooting situations involving a motor, more than half the battle is simply isolating the problem. Whenever there’s a working motor, there’s a load and there’s some sort of motor controller, ...

The Allen-Bradley Branch motor control components have been revised by Rockwell Automation. According to the company, this move was made to update systems where components are used to turn on and off ...

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 ...

Safety is a major concern in a good many motor-driven applications. This is true in industrial applications where motion starts when power is applied and especially true when power is restored after ...
